I haven't done the math, but I would be surprised if a Delta IV-H couldn't fly a similar profile, resulting in the first stage being in a low orbit. DIVH and LM5 have similar LEO payload capacities, and the mass of everything above the first stage (dry second stage, propellant, and payload) is ~90t for both. So, quick napkin math looks like it works (obviously there are a lot of other complexities I'm ignoring here, for the sake of simplicity).

All i wanted to say is that there are no possible payloads for this scenario (payload will be so small, a much smaller and cheaper vehicle could deliver it). It's not an operational configuration of DIVH because it makes no sense.
