Given what little I know, all the Mai- stories are the same characters, different story. A good example is to look at the two animes.

There are. AIR (Enter the Wired) has an ongoing translation, Tomoyo After (Baka-Tsuki) and Little Busters (TL WIKI) as well. And the translations of Clannad and Kanon may not be that great, I don’t believe people who’ve played them completely will bother paying 50-60 Euros for another copy.
I cannot explain why, but I’ve the feel that even uncensored versions would be useless (pirates are pirates :roll: ).
