There's another point to this. If anyone wants to build a

What would perform the control, communications, rendezvous and
docking? Could a Dragon fly around with 35,000 lbs. of module on its
nose?

Possibly. If it doesn't have the fuel capacity needed, you could stack
two Dragon service modules top of each other. Falcon Heavy gives you
plenty of options to "throw mass" at this problem.

Another possibility is the satellite bus that Orbital Sciences is using
for their COTS station resupply spacecraft.
