When you say acoustic electric, do you mean an acoustic with a piezo pickup, or an archtop hollowbody with traditional magnetic coil pickups? I've been experimenting with some ideas for the latter, and I have had a couple of requests for the former.
Electric guitar guys are a very conservative bunch, from what I can tell the range of creativity in guitar amps that sell well is "do you want to clone a Fender, a Marshall or a Vox?" I am working on some ideas that don't follow any of those approaches exactly. But you do have to understand what creates the kind of sounds that are popular and try to get the amp to behave in such a way as to emulate them to some extent, so there are a lot of similarities.
With an acoustic I would suggest a different approach. I think what a lot of acoustic players would really like the sound of is a large diaphragm condenser or maybe a ribbon mic setup playing through what would essentially be a high end PA. A mic allows for trying something like a single ended hi-fi amp and maybe a Lowther driver. You can get a pretty dynamic clean tone with a setup like that.
