However, if I remember correctly, I did see some designs for a new
SST
concept that utilized varible geometry wings. Not much came of it
though, at
least I dont think.

That's the now-ancient Boeing SST proposal. Boeing's engineers had
to tell management the fuselage could carry the swing-wing mechanism
or passengers, but not both. ;-(
