Ship/ideas etc

So this is for the far future, obviously not now, but I'm unsure of who Yamoshi should end up with. I have three choices I'm thinking of, and what are your thoughts on them.

Caulifla

android 21

Starfire, if i add any more dc characters. particularly this version is how she looks https://scontent-lga3-1.xx.fbcdn.net/v/t39.30808-6/269708494_10159787420533485_1244423954856174983_n.jpg?stp=cp0_dst-jpg_e15_fr_q65&_nc_cat=103&ccb=1-7&_nc_sid=2d5d41&_nc_ohc=VFaiScwYsJ0AX8v-JYV&_nc_ht=scontent-lga3-1.xx&oh=00_AfC-1oZhunoj_WQCZ7ntgzKtawEStHivUdw41yr3-tR1Gg&oe=64442DC6

Blackfire

lastly, should i introduce certain non cannon dbz characters like say Cooler. Lastly, what are your thoughts on space battles? i know in most versions, saiyans and namekians, and earthlings can't breathe in space, but i don't want every fight to just be limited to earth. Would that be something you guys are interested in.

And for the ship you can also suggest others i won't do harem but maybe open to polyamory ie 2 partners maximum .
