Yeah, I suppose Nightwing isn't a fair comparison -- the DCUC figures are giants compared to MLs.
I guess this could work after all, then, particularly since the plan is to put him with the 2K3 figures:

And yes, Jester, please do share a size comparison of Wonder Man to the NECA Turtles!
Incidentally, there's been some discussion on another thread about whether the NECA Shredder will in fact be 6.25" or more along the lines of 7". Considering that this figure is 6" and will probably approach 6.25" with his helmet -- and assuming that the NECA figures are noticeably taller than the 2K3 Turtles -- I'm thinking 6.25" might be kinda undersized for that line.
