Okay, first off, thanks for all the comments.
I followed drbindy's and meddatron's advice and cannibalized my DCIH Public Enemies Superman for a new head and, since I was trashing the figure anyway, used some other parts to address the cape issue, swap in better hands and add the belt.
Here's how Supes is looking now:

Better?
Next up, I started work on the third member of my Justice League - The Dark Knight:

As you can see, I took a sort of unconventional approach to Bats. I love the classic comic version, but I've really grown fond of Nolan's screen interpertation as well as the neo-classic look in the Arkham Asylum games. This was my attempt to combine what I thought were the best elements of the latter two -- darker color scheme, massive build but no chunky armor to limit his movements.
Much as with Supes, Bats isn't finished. But while drbindy is helping me out with the shield crest for the last son of Krypton, I have no idea what to do for Bats' symbol. Any thoughts?
