Murdoch, I think you and I will get along just fine.

It now has different rims and mudflaps (see sig) and the back-end sits slightly higher due to swapping out for ITR rear shocks. The tread on that can be found here: http://www.torontocivics.com/showthread.php?t=178260
The goal with mine was for more of a rally type setup and not so much a super-high 4x4 off-road type setup like you're talking. But that sounds like an interesting concept. I'm also planing on adding a rally light bar on the front with proper rally lights.
I've though about doing a CRV drivetrain swap. It's an ambiscious idea that would require quite extensive work in the back end. You'd have to cut out the entire rear sub frame section and replace it with the CRV rear subframe section. It's a lot of work and there is a lot of structural integrity issues you'd need to address.
I don't have the money or the time to try it, but I would if I could.
Not easy, but not impossible. If you do attempt this, let us know and keep a build thread updated with pics!
