The number of possible moon missions' architectures are probably near the number of heads that thinks about them...

But the main change I suggest already is in my article about the SLV: to send the moon-hardware for 5+ missions before the first manned mission with a cago-LSAM.

Of course, the cargo-LSAM must have also extra oxygen, food and energy to give two-three months (or more) extra life support to the astronauts (the only way to have the time for a rescue mission if something goes wrong).
