Can someone make a UK(and Northern Ireland) cup, with a big amount of teams?

I thought it would be really cool if someone could make an almost FA cup size competition or Scottish, English, welsh, Irish, and northern Irish teams. Of course my talents with the editor don’t reach this extent so I was wondering if anyone else was interested or could make it . That’d be amazing! Thank you

What you're asking is quite time comsuming but if you be patient I'm sure someone will make one soon as there usually is every year.

Yea I know that it’d take a lot of time. It’s just a request or an idea

Fairly certain one will be made eventually
