The problem you're describing - wanting better access to the higher frets - is most often solved by making a deeper cutaway or contouring the heel at the neck joint so there's less lumber in the way. Neither of these approaches necessitates changing the fundamental layout of the guitar - it's just trimming away some fat.
If this is your issue, BBQ, I'd suggest building a soloist w/ a short-scale conversion neck (Jags are the shorter scale, right?); this will take care of the cut-away thing for you... plus, just thinking of a Jazzmaster/Jaguar style body modded with a deep cut-away makes me cough bile! :tard:
