Batman:
This is going to be a sweet looking axe if it's done right. I've been thinking about this thing way too much!
The newer look of the curves is definetely doing it for me, very very nice. Definitely some potential for an amazing guitar here, I think.
For wood: Consider doing a multi-piece body, it's going to be very tricky to get your hands on wood of that size.
Have you considered alternate hardware for the axe? Possibly one of those larger gold delta-style tailpieces that are seen on some other Vee-style guitars?
Did I see you mention LED's a few pages back? Be sure to use those in moderation, as they can really make an otherwise classy guitar seem gaudy. Tasteful positioning determines wheather a guitar will be show-worthy or door stop material...
Spiderman:
If you're going to do this guitar, pulling no punches for practicality, do it, but be aware that people are saying things for a reason.
From my perspective, you're going to have a lot of issues trying to do the routing precisely, additionally, it's going to be tricky to get all the spots in the contour finished decently. Thirdly, you're going to have a really good time doing all the wiring and finding good spots for the switches. Finally, I think can't imagine it sounding very good with so little wood near the pickups.
Depending on which of these things are issues (if any) I would seriously consider revising the design. While it is a spiderman tribute, it's important to remember that at it's most basic level, it IS a guitar, a musical instrument, and I can see your enjoyment of it decreasing greatly if were difficult to play.
