I think it's a good idea but I think you'll find that the people here all have very different ambitions and goals for classic and getting them all under the same umbrella would be impossible.
Take myself for instance, I have a full time job, 40 hours per week. I don't have time to play super hardcore this time around, I'm looking for a more casual guild that still aims to clear all raids at it's own pace but the mentality can still be that real life comes first. I also have 0 interest in any and all PvP which is why I will play on a PvE server but I know a lot of people here want to play on a PvP server.
It's tricky when everyone wants different things. Best of luck to you if you manage to get it going though.
