Dude, get a used epi V for cheap and overhaul it. As much as I love trems, especially floyds, I can't see the Gibson buying crowd being ok with an instrument that has been modded in that way. Resale value may not be that important to you now, but there's a recession going on and you never know.
The OP is free to speak for himself, but I would wager that he doesn't have the money to pull in a Shred V (otherwise he could get a far surperior Jackson KV), and this is a very shitty market to try dumping a guitar right now, so he might be trying to make due with what he has even though it may/may not be the best move in the long run.
Real FR: $100-$150
Routing/setup: $100-$200 ???
That alone puts a cost of $200-$350 on the existing guitar.
Best case on an Epi V is $300 used after shipping because the odds of one on the local craigslist outside of a metropolis are nil. Thus, an Epi project = $500-$650 ASSUMING total satisfaction right there. There could be another $50-$250 desired for upgrading tuners and/or pickups (cheaper costs used offset by installation costs), which I'll round out to $125 for minimal upgrades, or moderate used upgrades self-installed.
Now you're at $625-$775 for a secondhand Epi V, which is 50-66% of the cost of a used Jackson KV2. If he took a bath on the Gibson and applied the "Epi cash" to the solution, he could score an amazing Jackson on Ebay... or he can throw $250-$300 at the problem using his existing axe.
