Sure you can; I've done it plenty of times before, and in fact, this
is precisely how the old-school 80s-era "serial port" networks used to
work.  The frame delimiters work perfectly for this very purpose.  You
may have extraneous bits left over, but those won't be a problem,
since a frame partially received with a dropped carrier is a discarded
frame by definition anyway.

The host PC would perform the bit-stuffing and unstuffing.  There'd be
a hit in software performance, but it's negligable with today's
multi-GHz CPUs anyway.
