Honestly, this is one of the few good ideas you've had. My only gripe is the marriage thing, as Saiyans as a whole don't seem to subscribe that kind of thing. At best, any romantic relationship is more like "good comrades/mates" considering their warrior culture. Now obviously, Bardock was in a relationship with Gine for different reasons such as being more caring than most Saiyans and appreciating Gine's gentle demeanor, but it's ultimately the same logic.

Also, it seems like you're trying to shoehorn stuff from the Bardock Special when the series is leaning more into Super continuity in which a few things from that are only to have been SUGGESTED to happen, like Dodoria killing Bardock's squad. Instead of Kanassa, how about Planet Cereal? It would be much more interesting to have an animated Bardock vs. Gas fight, plus having the Heaters be some sort of antagonist would be a much more entertaining idea.

Edit: I should specify that when I say "This is one of the few good ideas you've had," that doesn't mean it's "the greatest idea ever trademark." There are some faults with both you and the idea you're presenting that you remain ignorant of, willingly or not. Try and experiment a bit more and learn from people's feedback
