That brings up another little paper napkin design that has been
floating around : two four segment SRBs on a Delta IV Medium CBC,
attached from the thrust structure to the intertank segment, with an
SSME for primary propulsion. This would be the 'little Ariane V'
design. Any comments?

Yeah, us a RS-68 as its cheaper than a SSME.

Except for the fact that it can't make orbit on its own.

If you want to fly the RS-68, may I suggest the Delta IV?
