Sure.  I think its even niftier to encapsulate them on a DIP8 adapter of
course.  Since I will have the resources soon to do one or two fun things,
I'm checking around to see if there is a tolerable SMD matched pair that
enough people will like, maybe then making a batch of these boards would be
reasonable.

2k are not uncommon.  For example Ray Wilsons Music from Outer Space VCO
uses them.  If you modify a Synthi VCS3 for stability you'll wind up using 3
of them.
