Hi.
Feasibility is all about how
You determine it.
Prsonally I wouldn't dream of doing anything like that, a custom build from ground up would be far more feasible for me.
It's a lot of tinkering for shot down resale value and a pretty hefty wad of cash for the materials.
BUT, that's Your cab to tinker with, and since the asthetics are a huge part of it all (something that I won't deny ever), just do it if you feel like it's important to you.
"Better to regret what You have done than to regret what You didn't do".
WITHIN' REASON of course
