According to various sources on the Internet, but summarized in Comic Book Resources, three past TMNT actors have opinions on this matter: two for, and one against.
The people who played April O'Neill and Leonardo think it's a good idea; the actor who played Michelangelo does not, and had very vulgar choice words on the subject.
However, one issue comes up when looking at these numbers: Judith Hoag (April) has been in Michael Bay's films. She's assumed to be in his employ. She admits this, but that doesn't excuse her obvious bias for professional reasons.
The way I see it, it's one to one. I think other TMNT fans would agree.
