Just use one of the many obscure English clubs and their stadium in the game, there's enough of them to use.
They had to remake the editor, its a shame but its still possible to do the things you could in the old one, its just the clubs and stadiums etc won't be brand new.
There's always a way around things if you work out how, club colours can be changed through a file, search for it (everytime I've mentioned the type of file it says the post won't go through until a mod checks it).
The other stuff you can't do at all (like add feeder clubs) is hardly the most important.
It'll be a good step forwards once they work on it some more.
