"AS to JCM, as good as he is in the persona of Hedwig, his vocals are a relative weaknesss, and for all the talk of Darren Criss having this musician/band/mic experience background, his vocals lack both power and grititiness if the goal was to have a "non Broadway" voice. The question for Adam would be how good of an actor he is capable of for going for Hedwig's persona, not whether he would "over sing" his vocals. That would seem to be the least of the problems of Adam in the role."
JCM's actually being Hedwig is why the songs work in his voice. When he sings as Hedwig the songs are just an extension of him speaking as Hedwig. Darren's voice has all the power needed, and that power is coupled with emotion which is perfectly suited to the character and show. His experience in bands and as a musician comes into play more with the act of being a frontwoman. His Hedwig is more comfortable/natural on stage In that capacity and he feels the music more than most of the others. You can actually see the music moving through him and coming out as raw emotion.
I haven't seen enought of Adam as an actor to speak to what he can or can't do. My knee jerk reaction was, no, he's not up to it as actor, but I realize that's not quite fair because I've only seen him in a couple Glee scenes reciting material that wasn't much to work with. But I'd think if he was up to it as an actor he'd jump to do it, even just for a few weeks, because if his acting could match what he'd bring to it vocally, he'd be opening himself up to only amazing things.
