I think so. The key is putting the modular connection
interfaces of the radio at strategic points in the
signal/control flow path. The SDR-1000 is clearly on the
right track with its design in that regard.

If you start with mass consumer items such a generic PC's and
mid range sound cards yes. At least that is one approach,
perhaps the most economical one too.

Yupp, keep the number of interface connections to a minimum.
Also keep the technologically stable component parts on
boards (or even in separate boxes) segregated away from the
highly evolving ones.

With a little bit of forethought much of the alignment smarts
can be built in. If you look at most modern radios there is
very little to do in terms of adjustments for the various
tuned circuits. Components in the last 10 years or so have
been quite precise a pretty stable over time. So re-alignment
isn't often necessary.

Most definitely, and it just takes a fresh view of the design
problem and what the end goal really is and then figure how
to get there.
