I'm assuming you mean the one with the NWs, not the labs.
Personally, I wouldn't. I'd put her in a 1g.
I'd think she would be terrified being put in a tank with those cichlids. I would guess that she would cower in the corner, on the bottom of the tank. I would also venture to say she'd be sporting some major stress bars.
That's pretty much what happened when I tried to put a female in my 29g, with similar fish as yours. She never moved for 6 hours (with lights off). She practically swam into the net when I removed her.

I ended up buying her a 2.5g for $10, that she shares with 2 floating frogs.
All bettas are different, DD. The one I tried it with is rather tame.
If you try it, keep a good eye on her, and make sure the other fish aren't picking on her, and that she is eating.
Congrats on the Jewel fry!
