Which is incredibly wasteful. As I mentioned previously, it's like using a semi with the trailer unhitched to drive to the store. You can do it, but you might as well be burning money.
Except that the J120 is only used for Orion-only missions. ie. to the ISS. And there will be so few of those missions, that the savings you make on development and infrastructure for Ares 1 actually make the J120 the cheaper option. The DIRECT architecture is all about the J232. And 2 of those are cheaper than an Ares1 and an Ares5.
