Hows this sound for a silly idea:
The requirement is to get a /20 into a /24 IGRP domain.
The second requirement is that no static's can be used at all.
Create a second OSPF process on the redistributing router (ospf 2 for arguments
sake)
Create one or more loopbacks and put the 4 /24's on it.
Redistribute the ospf 2 into IGRP and IGRP into ospf 1.
You may need to do some tweaking on the border router, maybe policy routing at
worst.
