Below is what my goal was with my custom guitars. All would have similar body styles, neck radii and lengths (except as noted). The idea is similar to a good set of golf clubs: Cover several requirements with something that, generally, feels the same to use.
1) 25" scale guitar - H/H with Variax circuitry - no trem - covers acoustic needs (had this, but was forced to sell)
2) 25" scale guitar - S/S/H Classic Rock tones with trem and TONS of tonal options (had this, but was forced to sell)
3) 25" scale guitar - S/S/H Modern tones with trem and extra tonal options (paid for, but on hold for now)
4) (Future) - 28" scale baritone guitar - H/H (probably modern tones)
5) (Future) - 30" scale short-scale 6-string bass - S/S/S (similar to Fender's)
6) (Future) - 25" scale 12-string guitar - ?/? Classic Rock tones
