Leave it to NASA
If there is an easy way and a hard way they choose the hard way.

All that just so they can have one launch instead of two.

Huh?

They *are* going to have two launches - one CLV and one CaLV.

NASA calls it 1.5 launches.

Regardless of the nomenclature, your objection still makes no sense.

If NASA increases the number of launches they can use:
4 segment solid rockets already in production.
The existing fuel tank.
RL-10 engines for the upper stage also aready in use.

If they stick with the current architecture they need:
NEW 5 segment solid rockets
NEW taller wider fuel tank
NEW upper stage engine.


The first rocket is much easier to design and build then the second.
NASA is choosing the second or the hard way.

*Now* you are starting to make more sense. But your new points are
independent of your original point - that NASA was trying to have one
launch instead of two. They're not. Whether you choose to call it "1.5"
or "2". it's still two launches.
