its always worth a try if its something you wana do, the worst that can happen is that it doesn't take off and then all you can do is move on. On the other hand theres whole load of things that could happen, it could be the best thing you ever do, i'd say definitely suggest it and try some persuasion, if the other guys are up for it then go for it.
They might not be too keen at first but if you show them the potential of it then it might work, but yea, just to say it one more time... i say go for it, can't really go wrong can it?
what was your old band called? if you dont mind me asking... =S
