Tried a LP Custom today, my God the fretboard was so short!
I see your point, but from the other perspective.
On other guitars, there is so much space that is really not neccesary, a solo doesn't need to be right at the top of a fretboard IMO.
Good luck with your search, I haven't played too many epiphones, but I got lucky with mine. Maybe the maple neck really brings it alive
