Actually, the Avengers did have Mother (a man) and Father (a woman) in charge of their agency but Father was a late addition and I'm not sure if she appeared more than once, when Mother was incapacitated. That said, the portrayal of the women became increasingly tongue in cheek. Father was pathologically clinical and, as you say, Peel quit to become a housewife.
Palmer was fine but a bit of a cipher in her two episodes. Muldaur was probably best able to inject competence and personality although Charlene Masters was cool too. It's only really Rand, Smith, Landon, and Mears that have discernable personalities out of the yeomen and all four of them were involved as a love interest for another character. I think Uhura does well to project so much competence and personality while avoiding the love interest pit trap.
Roddenberry took active steps to hamper Rand's development by encouraging the writers to keep her as Kirk's valet rather than letting her man other stations. That might be why they struggled to find things for her character to do.
I almost forgot I'd done this... a little cameo for Rand in the Tholian Web...
