I honestly believe kemper would come up with something special if they did this. I would doubt they would do it the way line6 and Vox have done modelling guitars. Also they would - I'm guessing - wouldn't do a modelling but a profiling guitar so maybe what little snags the Variax has wouldn't necessarily be the same for the Kemper guitar.
Also would be great not just to be limited to a few guitars, a banjo & sitar but you could have anything that's been profiled that you wouldn't normally find on the Variax like a Gibson SG, a Fender Starcaster or even a 1950s/1960s guitar like a Kay or something like that.....we can but day dream!
