Sweet! Keep me posted if you decide to buy it. WB has it on sale for $20 at the moment:

As far as size goes, I have mine in storage (until I finally build my shelves here in my office), so I'm not sure how he compares to DCUC offhand. I think Batman (the only one I have from this set) was a bit taller, but he's not Bruce Wayne, so I could easily justify any size differences with my DCUC figures when I displayed them together.
Wonder Woman may be too tall for your purposes, though, as the DCUC female figures tend to be fairly small.
