Shang Tsung absorbs the souls of opponents he deafeats, and then is able to completely mimick them in order to use their abilities. I do have something similar in mind - shifting into completely diffrent forms with diffrent abilities - only without the 'soul stealing' part, having a preset range of froms he can shift to that cannot be increased.
I don´t think there would be any problems with that, as long as it requires at least one tick of charging to perform, and doesn´t have a "This isn´t even my final form"-kind of thing to it.
Edit: Schradinger, If it´s okay, I´ll have Killstreak teleport to your location after your next post, then bail.
