I think the key to making it really fly would be to hold some short sprint
contests using PSK63 only. That way you could get a lot of guys to try it
without a big commitment of time and effort. As it gains acceptance thru that
and word of mouth, it could be added as an optional mode in more
The IMD shouldnt be a significant problem unless something is overdriven.
However, you see that with PSK31 and to a lesser extent RTTY fairly often on
the bands, although most of what i see is 60 cycle hum and audio harmonics
related to that, rather than just pure overdrive. AFSK, etc., is

Just because a mode is better doesn't mean that people will want to use it,
though, and I
