That's probably more a question for somebody like bruce on rcmodelreviews. However, he will probably say that dsm2 is s**t 
On a more serious note, it's hard to say definitely. It ia a fact that dsm2 uses two frequencies, and stays on them. The dji downlink is probably pretty data intensive, and as such will use a lot of the 2.4 spectrum, and could likely step on a dsm2 rx.
Best way to know for sure is to have several dsm2 systems running on the ground, with tx's maybe in range check mode. The get the inspire close and see if they stop working.
