If you can find a sized right male, you can always try, what's the worst that could happen, one gets dead.
I''ll give you a couple examples of my experiences with that, a buddy had a large female Tomocichla tuba(12"), I had 3 slightly smaller males (10"). I gave all 3 males to him, his female killed 2, but mated with the last live one, and in the I ended up with half dozen juvies.

above the female tuba is guarding a stream of brown eggs
Another example, I had a 10" female haitiensus that killed every hait that grew up with her.
I finally found a 12" male, and within 2weeks of putting them together , they spawned, and spawned again and again for a few years.

I will admit putting adults together can be iffy, and adults are often much more expensive.
The pair bonding seems almost always stronger with pairs who chose each other, and usually had a better spawning success rate.
Adults are usually way more expensive.
Where I lived, I could usually get juvies of just about any cichlid for @ $3 each, so if a pair formed and killed off a few in the process, the financial pain was not as great as buying a $50 or more adult fish, and finding it dead the next morning.
