I'm into shortscales, my favourite gigging bass is a CIJ mustang, but I also own a couple of musicmasters ('71 US fender & Squier Vista), a danelectro longhorn & a 32" daisyrock elite. My daughter also has a '71 musicmaster and a couple of daisy rocks, so she's a bit of a shortscales connoisseur as well and would be able to comment on the "cool factor" from a teenager's point of view.
The best thing about my mustang for me is that, even though it is a 30" scale, it has through-body stringing, so a set of 32" Thomastic flats fit on it perfectly. Also the neck is very narrow & thin (a guitarist mentioned recently that it feels like a particularly comfy strat neck). With my ideal strings (TI JF 324) I can still get an optimal amount of relief in the neck.
I nearly bought a mini precision when Fender made them a few years ago, I think it was around a 27"or 28" scale, but I was put off by the lack of choice of strings that would fit.
I'd like the opportunity to try a prototype and I'll be more than happy to report back about what I like and don't, giving reasons and suggesting possible improvements.
