Yeah, I'd say guitars are heavily based on aesthetics, but not entirely. One of the reasons why I switched from a Les Paul, which was the guitar shape I loved the most before I started playing, to a Stratocaster was that the Stratocaster was just that much more comfortable. The LP body is basically just a block of wood with a cutout for your hand in comparison to the contoured body of the Stratocaster. If I had to buy an LP-style guitar again, I'd want at least a belly cut on it.

Look into a "Recording" model Les Paul (or the newer "Iridium" model if you don't care about the low-impedance electronics) - they have exactly that. The main complaint is usually the weight though - of the two I have one is 11lbs and one is 15lbs (!!!).
