I know this is just a meme but this would unironically be a good move.
I'm meh towards her, but people outside /a/ generally like Caulifla (judging from reactions, she's the most popular unfused U6 Saiyan by some distance) so finding a way to bring her into the series more often without asspulling constant universe crossing would net Toei quite a bit more money.
Marrying her to Goten would def give Toriyama his raffs and pull Goten back into the spotlight for a few reasons: he is now married to the series' first canonical female Super Saiyan. The two can fight and get stronger, which will let him get SS2 and possibly SS3 before Trunks. Caulifla will also be right next to Goku, so she can learn how to go SS3 and SSG.
Most importantly, we'd get the series first three-fourths Saiyan hybrid. This would make for a great contrast between him/her and the 1/4 Saiyan kids Pan and Bra (as well as Uub). 3/4 hybrids will probably have saiyan waku waku instincts but still have human emotions, so it's like Gohan on crack, but with a more positive outcome.
It would also be proper character development for Kale. She was always Caulifla's protegé, so it's been established she's probably going to take over the gang. Separating the two would force her to get over her lesbian autism.
It would still work if she went for Trunks, but it wouldn't be as funny without Chi Chi going berserk, and Trunks still has Mai to contend with.
If Tori was a hack, he'd cut out Kale's growth and give her to Trunks.
I'd personally rather Caulifla stay in U6 but her settling with Goten is unironically a very strong move. I can see why people like the idea.
This is all probably too positive, on-topic, and faggy for /a/ so:
Waifushitters need to get gassed and Cucklifla is getting spread by CHADba.
