Unfortunately, porting things from the KotOR to TSL is a violation of the EULA (End-user license agreement) and so folks aren't really allowed to do it. There's also a rule on the forums against porting. The only way I could see around it would be finding a head in TSL that is similar to your Revan and then creating a new skin from scratch to resemble what you saw in KotOR.
As of 23JUN13: I released a new small texture mod! Check it out here
