I don't have an amp modeler yet, surprisingly. What you're saying makes sense, and always in the past in other groups we had acoustics through the PA and mic'd the amps separately. I'm certainly no tube snob, I still use my old Fender M-80 Chorus though I don't use the distorted channel, I use (old) outboard gear for tone coloring. It's loud enough that any venue that needs more volume needs a PA for sure.
Having a single unit to handle vocals and an acoustic is pretty attractive, but probably I'm not going to find anything to handle vox, acoustic, and an even slightly distorted electric tone to my liking. I'll probably just wing it for a couple gigs and see what seems to be the biggest holes in what I'm wanting and go from there.
I've not ever heard an acoustic sim I liked. That said, I've warmed to other effects over the years so maybe I just need to take the time work with the sounds.
