riverat, I'm not sure if you'll actually see this reply - but I took a 6 string Tune bass and threw it into Stick tuning [5ths bass/4ths treble..] with the thought process being if I can't do it on 6 strings, I certainly won't be able to on 10....
A few years later, more like several years later - I attempted 3x [the first time I bailed... felt I was not good enough...] to purchase a Stick, but in the end I got two very different instruments which for me oddly enough made more sense: a Warr 12 string that's in a reciprocal tuning but with a twist: melody on top, bass on bottom... and just now, I purchased a TT Mobius Megatar with those fanned frets which you mentioned - with a twist as well - it's tuned like a 12 string from top to bottom in 3rds !!
I see you have not been here in a while, and hope that in the meantime you've been able to find an instrument that works for you, and is affordable.
