^^ Of course, unless I'm misunderstanding you. If you're using all the inputs on the recorder, the two XLRs and the 1/8" stereo input, the deck will record the XLRs as a stereo pair in its own file and the 1/8" as a stereo pair in its own file. It won't record them as one big 4-channel file. At that point and in theory, you could even split them into 4 mono tracks with the right DAW, the -60D just doesn't have it as an option.
