Life(son)'s axe

Rush's Alex Lifeson finally has a Gibson LP to his name & it features a Floyd Rose locking whammy bridge. The instrument per se looks very attractive but I'm more attracted to the rear of the instrument for its tailored neck-body joint. As the guitar was created in the image of the Les Paul Axecess, it looks like this: CLICK

I'd somehow wish that Gibson make this feature standard in some production LPs for dweebs like me who could benefit from less bulk at the heel.

Titanium Rose

Floyd Rose goes one-up by offering its tank-grade bridge in a titanium version (this debuted last year). The material worth aside, we need to listen if there's any tonal difference in view of the material used. The question is, which guitar manufacturer would make this bridge accessible to those of us who wish to try (by incorporating it in their instrument)? Is it practical to purchase it as a replacement item just for the sake of trying? It's not cheap, yes?
