as long as piccolo learns kaioken, everything will be okay, he can regenerate, his body can change size and elasticity at will, he should be able to pull of a times 20 kaioken with little to no consequences... The main problem so far is Cell, Cell will be able to get the samples and techniques of all other namekias, guru included and the ginyu forces, he will look different from the Cell we know, he will be able to do much much more... Remember, Cell was able to have King cold and Friza dna and techniques on a short amount of time, the more the plot changes... it will only makes cell stronger and harder to kill.
Yes everything is well done with the released potential of Yamcha, piccolo, Kami, Krillin, chaotsu, Roshi they will be able to defend the earth against the freezer weapon. the fusion of Nail and piccolo it will always be possible by using Abo and Cabo who can merge together to create Aka, can beat the whole Z team and force the fusion between Nail/Piccolo or Kami/Piccolo in any case there will be a fusion . Good idea not to send the Ginyu force to earth it will be the end of the planet and even if he survives the cell will have obtained the DNA of the Ginyu force with the capacity of each one they dangerous given these powers has a genetic perfection like cell it is really sought to create another Janemba
As for cell, I have a proposal: in my opinion, it went a little too fast in the past. I propose that he increases his power as a safety measure so either he absorbs all the humans and truncks, or he absorbs all the cybors remaining in his timeline, in all because he should have enough power to beat C16 C17 C18 and all Ssj without problem and without having absorbed C17 and C18 he will always do the tournaments to test his strength. for the original timeline cell bulma could reprogram him he would be a really good sparring partner as he too will continually gain strength.
