Hmm. That sounds kind of tough, but if the meter changes are at least kind of intuitive it might not be that bad.

Just my opinion here, but I kind of doubt you'd use an acoustic that much. It's possible, but I find that I only bring mine out if 1) I can't use an amp or 2) I need to use it for some sort of quasi-public performance sans drums. If I performed a lot more acoustic-y music I'm sure it would be different. But I usually stick to electric, even after playing exclusively acoustic for probably 10+ years. Electric guitars can cover an awful lot of ground.

In the end, you know your needs/wants way better than I do. I guess I'm just giving you my experience to say that it's not as crucial as I would have thought. As always, YMMV.
