"Bi-amping" an integrated without another amp?

I have an integrated amp with dual speaker outputs. (Rotel RA-1060) I am curious whether it is possible (or useful) to bi-amp the speakers by connecting the A channel to the high/mid and the B channel to the lows. I suppose it depends on whether the internals are equivalent to 4 mono amplifiers or if it just splits the output of two amplifiers (equivalent to bi-wiring). I plan to upgrade the amp in the next year, so I'm not interested in adding a power amp right now. The speakers are already bi-wired from a single output on the amp.

Anyone tried this? Thanks!
