It's perfectly possible - in fact I did exactly this at my first ISP, 
Pavilion Internet in Brighton, 10 years ago. Multiple serial boards are 
available, and just look like several /dev/tty connections. Set them up 
to run PPP, and put a modem on each of them and you're going. It looks 
ludicrous (we resorted to velcro-ing the dial-up modems to the wall of 
the machine room), but yes, it does work.
