Should I buy girlfriends for my boys?

Hi r/budgies! I'm coming out of lurker mode to ask this question. I have two male budgies, my estimate is 7 years old (the animal shelter stated they were 3 years old, and I adopted them around 4 years ago). They are good companions for each other, but after seeing a post here with pictures of all the budgie couples, cuddling and smooching, it broke my heart that I'm keeping my boys from having that kind of love.

I planned to adopt 2 older females. The problem is this: we had a female in the flock once (she was 10 when I adopted her, she lived about 1.5 years and paired with Jimmy) and it drove the boys crazy. Brother turned against brother and they fought to the extent that they drew blood and one lost a toe 😢 My assumption now was that the single female caused the boys to compete, however, now I'm worried that any females in the group will turn the boys hormonal and aggressive, even if there's no need to compete. So that's question 1; could the introduction of females cause fighting again?

I did kind of assume that the boys would settle with one partner each. However, that's question number two, do you think the boys could both try to catch the same lady in their Pokéball, leading again to competitive behaviour? And one lonely female? Or do you think they would pair up and settle into two sweet couples?

Let me know what you think, and what your experiences are! I want my boys to experience true love!

Thanks, Becky (Obo. Johnny and Jimmy)

I attached pics for fun. Jimmy and Johnny are the green and blue respectively. Jimmy always looks a little messed up, because he survived a battle with megabacterium a few years ago so cut him some slack. The little white angel prince is Jerry and he was the light of my life until he sadly passed away earlier this month during a kidney tumor removal surgery. The cockatiel is Scootie, one of our 3. They live rent free and free flying in our living room/office.
