Introducing female wrasses when males are already present - thoughts appreciated

[gregzz4]

Back in my early freshwater days (more decades ago than I care to mention) I bred Bettas
The only way to safely add them both to a tank was to add the male first and wait for him to establish himself
Then you'd float the female in a suitable container that allowed him to see her
He would then start to build a bubble-nest and the rest doesn't apply here, but suffice it to say that if you put the female in first, even though she's only half his size, she'd kill him

Here's my situation;
I've read that adding female wrasses to a male-established tank can result in female deaths
I have a male Solar wrasse, and a male Lubbock's wrasse in our DT
I came across a female of each and they are currently in QT
I don't want to remove the males from our DT, nor do I want to see the females thrashed
I was thinking, when the time comes to introduce them to the DT, that I would put the females in a floating container and allow the males to go bezerkers for how long it takes for them to calm down, and then release the females when the lights are off - or something along these lines

If it really comes down to it, I would have to put the males in the QT while the females establish themselves, but I am trying to avoid any stress I can for both them and myself

Any thoughts/insights are appreciated
