Had a discussion about this on another thread, talking about any code / electrician issues. When I had my runs put in, I had a tandem breaker that allowed two breakers on the same phase with a handle-tie. Not sure those exist any more. I went looking last night. I could not find anything. I found youtube videos of people installing that way (and not a switched/un-switched) but two separate feeds. Typically for a kitchen it is split phase -- two live, 1 neutral with a dual breaker.
If you can't get a dual breaker, single phase, with a handle tie, so that you can turn both of them off at the same time, they you are probably better off having two outlets really close to each other and tie the grounds together between them. Your code likely requires that if you have multiple live conductors into the same j-box, then they must be able to be turned off all at once.
Had a good laugh about the wires nest you are dealing with. I once had a house built in the early 60's when babies were still a booming and housing was needed and quick. There was no GFI in the powder room so I added one, assuming the wire that continued was for the ceiling light. Popped the GFI once. Bathroom light stayed on. Kitchen light went out. Garage light went out. Outdoor outlet went out ... you get the picture :-)
