So long as the novelty handset + mobile phone combo has both sufficient
dynamic range +and+ bandwidth, I don't see why it shouldn't work.
In fact, I'd mostly be concerned about the dynamics - the bandwidth should
be just fine. I don't believe a modem needs much more than the regular
300Hz - 3KHz of a standard POTS line.
Then again, duplexing (or lack of true full-duplex) might be a hindrance.
Try it!

Have any of y'all tried using one of those novelty
"retro" cell phone
handsets in an acoustic coupled modem? I wonder whether their output level
and mic sensitivity are sufficient, and whether their dimensions are close
enough to a good ol' Model 500 handset to fit an acoustic coupler well.
I may just order one up and try it, but I figured I'd ask if anybody else
has tried it first. It would be silly fun to dial up over my iPhone with an
acoustic coupler attached to my TRS-80 Model 100, or the DEC LA12
Correspondent terminal I have on the way from the ePlace. Not that I know
of any 300 baud modems to call up, though...
