Irish League Restructure

I was interested in restructuring the Irish League and was just curious if anybody would have advice or input into things to be wary of when making somewhat drastic changes like this to the original FM database.

I already used an existing custom database for the Irish Lower leagues so I could play with my local team Birr Town and try to get them promoted to the top tier but I didn't notice until I had won the 3rd division that the way the Irish league format works, if you are in the lower counties leagues you have absolutely no means of progression beyond the 3rd tier and cannot gain promotion into the 2nd division. Which to me seems very flawed.

I feel like the way the Irish League, in general, is structured seems to be pretty bad so I wanted to imagine a scenario grounded in reality where the league had a takeover and was changed to a promotion and relegation format for 4 or 5 divisions with different numbers of teams in each division.
This change could be funded by an investor that saw the League of Ireland as an interesting place to branch out and gain positive exposure.
My idea for an investor was Guinness as they already have a strong link to the identity to Irish people and could see the growth of the national league as a way of investing in the locality. and improving the national game. From what I have just seen from quick research online Guinness as a company had made significant profit margins as of recent years (3bn in 2017 alone!) So maybe the COO's are sitting twiddling their thumbs wondering what to do with all that money burning a hole in their pockets. Well here's an answer!

Currently, the total prize money allocated by the FAI for all the teams in the official league structure ( Premier and First Division) is €475,000.
That amount when it is stretched out across all 20 of the existing league teams is tiny and leaves no room to manoeuvre when competing on an international scale in club competitions, neither does it provide any ability to improve club structure and keep hold of promising youngsters.
I would change this allocation money prize fund to a much larger amount that would allow clubs in the top division to have a good ability to form well-structured clubs that aren't on the risk of bankruptcy as well as allowing the wealth to trickle down the football pyramid, giving lower divisions a portion of funds and a means of progression.

I imagine this resulting in Ireland beginning to take the shape of other continental European leagues, like a Sweden, Denmark, Belgium, Scotland or maybe even a Holland.
It would be interesting to see what happens when Ireland has the ability to nurture it's own talent instead of them all going to the UK immediately after being poached at 16/17.

I also had another idea that may or may not work as an aside that follows the Red Bull model when it comes to football where Guinness could take ownership of a team in Ireland. Shelbourne, a central Dublin City team that is in close proximity to the Guinness Storehouse in Dublin seems to be a good shout for that as they have a strong history of success but have fallen on hard times recently and Guinness could see them as a good team to buy with their location.
Interlinked with Shelbourne could be a network of other clubs across the world where Guinness have a presence, either in manufacturing or otherwise.
Guinness is produced in a bunch of countries worldwide so possibly in the cities where it is manufactured the company might purchase a local team as a way of giving back to the community ( Or to curb public appeal from the toxic fumes that they're putting out - who knows) and these teams could be given an improvement in infrastructure that would allow them to produce and allow them to act as a hub to recruit good local players that the Senior Affiliate club could have a look at when it comes to their own recruitment.
It could lead to some interesting regens at the very least.

Locations I've found where production takes place by Guinness or third parties include:

• Dublin, Ireland
• Toronto, Canada
• Nassau, Bahamas
• Lagos, Nigeria
• Douala, Cameroon,
• Bali, Indonesia
• Kampala, Uganda,
• Windhoek, Namibia

in addition to those, I could look at other European cities like the Red Bull Model to find one with a healthy sized population that isn't encroached into by any larger clubs likely to eat into recruitment that can serve as a good tool when it comes to getting regens.
I'm unsure about that so far but it's interesting to think about.
