I wonder what the chances are of this working on newer '030's, such as a PowerBook 180c or LCIII? (both of which require 7.1 w/ their System Enabler) I might give it a go over the weekend.

I remember about 10 years ago i once managed to hack up a copy of 6.08 with resources out of System 7, and i actually managed to get it to boot on my LCIII, although once it got to the Finder a dialog box came up saying that it didn't support that model Mac I might have to have another hack at it one day.
