Crazy Dragon Ball Z/Super Idea

So, I was just listining to music and reading some fanfiction of Dragon ball z where a guy becomes the copy of goku mr. popo has from dragon ball and has all of the memories of the guy and both goku and kakarot(preheadbonk goku)

when I thought of a crazy idea, someone becomes cell, and learns the multiform technique while in future trunks timeline before the androids kill future gohan, and after said androids kill gohan he absorbs both androids, and then in perfect form uses the multiform technique and kills the copy, but leaves a single nucleus alive, then the copy regrows and has a huge zenkai boost, then he conjoins back with the copy and his power has been multiplied, he than makes a lot of copies, and does the same thing again, kills them all leaving a single nucleus, and then reconjoins

the power he would gain, well, I think after three or four times doing this he could make berus use his full power and be serious and possibly tie with him.
