Actually, they aren't much different than an AM design, except that
generally, you use quadrature detection for demodulation, and that you have
a deemphasis filter. The I.F. bandwidth is different, but pretty much
everything else is the same.

It wouldn't be quite the same. You would be clipping the sidebands, and
experience quite a bit of distortion. A 110kHz filter is about as narrow
as
you can go.
I've been meaning to come up with a tuner that would be in the class of
a
McIntosh MR78 for the past couple of years, but something has always
come
up. Maybe after my current project, I will do this, if there is enough
interest.

I hear that FM RX's are pretty complicated affairs. Most FM DXers it seems
just modify commercial sets. Reduce bandwidth from say 230Khz to 110 Khz.
I
suppose that going this way has quite a lot of merit. Cheaper probably.
