Lots of reasons:
The less tickets they have, the more they can charge, Selling six months worth of tickets for $998 is one thing, but when you have double the amount, the more people might balk at that. Ultimately, as high as the demand is, it would cheapen the brand. If there are two concurrent NY productions, the one at the Rodgers suddenly becomes less special.
They're also about to have three additional companies nationally, not to mention a London production. And yeah, the show is basically minting money, but all of these additional companies cost a considerable amount to put up. If they were to take over another Broadway theatre, they would have to build an additional set, cast another production, hire crew, build costumes, etc. That's not cheap.
I also think, in general, it would be bad press for them. Sure people would buy tickets, but it reeks of hubris to open a second production in another theatre when no other show has done that. There is always a high demand for Broadway houses, and such a move could easily be seen as greedy and unnecessary.
I am a firm believer in serendipity- all the random pieces coming together in one wonderful moment, when suddenly you see what their purpose was all along.
