That would be fun to figure out; the weight of the aft skirt and its
engines versus that of the LEO payload.
The Atlas H 1/2 stage weighed 8,038 lb according to Encyclopedia
Astronautica; payload to LEO is 8,000 pounds, so with a lightweight
aerodynamic nosecone, who knows?

Hmm, and can you upgrade the engines at all?

Might gain you a bit more.

So.. what could you do with say:

200lbs
500lbs
1000lbs

I think the first 2 are basically "small sat" type things.

1000lbs, a bare minimum once around capsule?


You'd be able to strip some weight off of the 1/2 stage because it
wouldn't have to separate, so the plumbing could be simpler.
It'd be a mighty low orbit, but you might be able to do it.
