These won't be back, as it is a legal issue.
It's not really a question of what we can do (which is pretty much everything any other guitar company can do), but more a question what we will do, and that's determined by how far outside our normal production lanes it goes. We aren't going to agree to do an original body shape based off a sketch. That's way too much R&D time. But there are all kinds of things we will do that don't upset the natural flow of things too much. If you want something you don't see just contact the sales department and they will let you know if we can do it.
The biggest gripes we hear about this come from people who don't understand how large scale production works. They ask for something that sounds simple to them - and is simple when one guy is building one body. When we tell them "no" the get persnickety.
As much as I would love to see you in your mesh half-shirt, the neons won't be back...at least not in their old form. There was an issue with the paint itself that couldn't be resolved.
Solid 3/4" carved tops are expensive to make. People are willing to pay that on fully-built, prestigious guitars. They aren't as willing to pay it on for an unassembled part. It just doesn't compute in their heads that a body they still have to build themselves should cost so much. The move to double-lams was Ken's solution, to be able to offer a carved top at a more reasonable price. There were feelings from the execs going both ways, so who knows....maybe some day we will offer a true carved top again, but it won't be any time soon.
