Delta V Heavy as a manned launch vehicle?

Gemini could, and Gemini was very heavy for its capabilities,
in modern terms.

Two Geminis would meet the OSP mission requirements.


Two modified Geminis, maybe, of the type planned for
Air Force use. To meet OSP rescue requirements, a
vehicle would really need to have a docking hatch.

No docking hatch, low pressure cabin, different cabin atmosphere from ISS and I
wouldn't want to be the one that had to get an incapacitated astronaut into his
seat.

And besides, Gemini itself has been out of production for many years.

The point is not that you'd make an exact copy of Gemini, but that you
ought to be able to meet the requirements with something of similar size.

I don't think that necessarily follows. After all, the things that you'd need
to do differently generally add mass to the design.

And modern materials, manufacturing, batteries, and electronics will
all reduce the mass you'll need. It's hard to say if a modern Gemini
with such changes would be heavier or lighter than the original.
