You'd get the usual penalties from being booted from a cabal, and the usual deaths for alignment change.. its not a deny offence though.

Align changes means outcast which means no communing for clerics. It gets very hairy for align-restricted classes like Paladins, Healers, Necromancers, Shamans, etc. Switching aligns on these classes interrupts game balance, so you can probably assume major gimpage. The same goes for align-restricted races. But if you go with something that isn't restricted (e.g. human warrior), then you can probably get away with less gimpage. It's possible to do what you want, but i'd wager all my money it wouldn't be fun in the aftermath. Seems like a waste of time and effort, especially to make it to the point you described, to piss it all away...but people have done stupider things.
