I think for typical synth signals, that is V rather than mV regime it 
would actually be pretty good.  Other than the odd looks I don't see 
much of a problem.

I don't think they would fail hard just after 100 cycles, but that's 
something you can even try out.  Do you really care in this 
application if the contact resistance is 300mOhm vs. 25mOhm when new?  
Is it much of a problem that you occasionally may have to pull a pin 
and re-seat it?  Yes, I think I'd get several years of lifetime out of 
it, YMMV.  You could stack two sockets if you think this is going to 
be a big problem, that way the top socket can be exchanged when it 
wears out.  Likewise the resistors could be soldered onto pin strips 
so they are a bit easier on the socket, however they'd also get a bit 
bulkier.
