short answer is no, this is impossible. but impossible just means you have to be clever about how you do it

the easiest way, is to get 4 gameboys, 4 copies of LSDJ, sync them all together and only program one channel on each gameboy.

there is no such thing as a sound chip in the gameboy, everything, (audio, video etc) is done by the CPU, its a custom chip made for nintendo that is a sort of all in one thing. the only extra chips are some buffers and an amplifier (which doesn't even get used when prosounded)

as for doing something like having two CPUs in one gameboy, i am working on an idea which will be one gameboy with two cartridge slots, that would allow you to run two copies of LSDJ from one gameboy.

to split the actual channels up from one CPU is impossible, and you would have to start from scratch, possibly even go as far to have a custom cartridge with 4 audio processors on there, and all the sound would be made by the cart and the gameboy is nothing more than an interface. but again this would need custom software so you wouldn't be able to use LSDJ or anything like that.

you can do what some people do which is pan one channel to the left, and all the others to the right, it sacrifices stereo sound but gives you two channel audio, which can then be summed again by a mixer to give you stereo after you have done your effects on it etc.

if you were to pan your audio with two gameboys, that would give you all 4 channels on seperate mono lines, then if you mod one gameboy to be small enough to fit inside the first gameboy then you have one gameboy with 4 mono channels out.

EDIT:  Re-read your post... that's totally doable with 4 units + 4 carts + a sync box of some kind, I thought you were referring to 4 stereo outs from one unit.
