I would not do it. I have heard of people using home theater equipment with (double duty) stereo equipment. To me mixing and matching unlike equipment or for unlike purposes complicates the system. Keeping things simple always sounded the best to me.
Once I had a stereo amp, preamp, DAC, and CD player as a single source system. I took the preamp out of the system and it sounded better, because my DAC could act as a preamp.
