umm...i dont think you're crazy, just...odd
sorry, but i think that that thing wont come out right. why? here's a few things that WILL go wrong with this:
1: floyd rose bridge is a lil wider than fixed/tune-o-matic/vintage 6/vintage 2 bridges. that means you will have to route out your body by quite a lot.
2: not only the bridge, but your pickups would have to be routed out to be slightly wider, so they could be installed with the 'F-spaced' pickups. and i do believe that the bridge pickups are wider than the neck pickups
3: the neck would have to be replaced. this is becuase at the nut, the neck for a floyd rose is usually normal width, how ever, around the 22/24th fret, you'd notice how wide the neck becomes. not only that, but for a floyd rose, you would need those lil nuts to be installed. either you would have to get your first fret routed to install that, and make your first fret TINY. OR you'd have to cut the neck pocket/cavity to become slightly wider and install a new neck.
what would happen if you keep the normal neck? humm...you heard of those GODIN guitars? i dont know the exact series, or the name of that guitar, but one of their guitars(or maybe more...?) use a normal spaced neck, or something that is slightly smaller than FR equiped guitars. this would creat a problem as you'd notic that both your high E and your low E strings would either constanly slide off of your neck, or around the 12th-22/24th fret, it wouldnt even be on the neck! it would just be flying else where
sorry for bursting your bubble, and i'm not saying that it CANT be done. it would just require you to do an exact job.
but if you're thinking of getting a floyd rose just for the dive bombs, why not getting a vintage 2 screw bridge(the thing that
yngwie malmsteen has)? i mean, you can do some insane dives on it, and if you losen the spring tension on the back of the guitar, that would raise your bridge from the body. this will allow you to literally PUSH the bridge into your guitar, which would stretch your notes/strings, and would replicate a floyd rose. this actually works wonders with my first frankenstien guitar. i mean, i have a stratocaster replica(i made it a frankenstine guitar...) with the vintage 6 screw bridge. the 6 screws prevent me from doing dive bombs, how ever, i can push the bridge into the body, and i can do the same stuff with harmonics...
g2g, will come back later, so if you have any questions, let me know...
