Well, that's going to up the cost; for some people, that might be an issue.

Also, I dunno if there are people out there with table-top 11/15's-20's (they
did exist BITD, I worked with a table-top one), but for them, an additional
box might be a hassle too.

I guess I don't see the harm in making it two SPC (quad) boards? A flat cable
or two to connect across (I dunno how extensive the interconnect requirements
between the halves would be, and I have forgotten what the inter-slot
interconnect capabilities of an SPC backplane are - ISTR that it has some
bussing on the F section pins) would be easy and cheap.
