Is there any easy way these can be split back to single dedicated lines? (excuse my horrific diagram)

There seems to be 2 double pole breakers, one is 15A/15A the other is 15A/20A! The wires are split between them. It seems like (from my research) this is wired as a split phase shared neutral (as per here: Term to describe two circuits run through one /3 cable) and in the receptacle i can see an entry and exit wire so i assume the exit wire goes off to the dishwasher. So turns out in the sub panel off the main panel there is a cable for the dishwasher and washing machine already! So i figured as the washing machine one goes over the same area of the basement i want to move the laundry room too i could pull it down and use it but now it gets odd.

The plot thickens lol (im ditching the oven circuit for now for ease of understanding but will likely look at full upgrade anyway) I my pretty sure the sub panel lights and outlets (which service a small area of the basement only) can be wired to the existing basement lights and outlet circuits which could reduce it by 2 x 15A (I think this small section was wired this way to prevent ceiling tracking.
