If this was a smaller game, I would be in. I know i kicked around interest before, but every "large" game I have gotten into here has been little more than wasted effort. Put the time in to a character and then not be able to use it seems to be the norm. So I would want to see forward motion of some kind first.
If this gets going and someone drops, I would consider replacing into their spot. Until that time I will be watching with some level of interest.
