well you could get a short/medium scale 5 string made, i've read in a couple threads that talk about only being able to use EADGC tuning but someone(name escapes me) tunes BEADG and it works just fine with the short scale 5'ers, i know for a fact that most of danno's basses are 32 and he says they work fine for him(most of which have 5 or more strings)
so basically you'd be sacrificing the scale length, but if the shorter scale length is not that big of a deal to you and you just want an LD bass then i say go for it :-)
