I dont see a need for this since Clickies do not have a set sexuality. They are whatever a child wants them to be.
They already sell plenty of duopacks with two men or two women, though it tends to be two pirates, two soldiers, two fairies or such. Maybe those are all meant to be couples?
Kids will put whatever clickies they like together, relatively few clickies are sold as a complete family after all. Often its one parent with children and kids may just not like the shirt of one of them and replace that clicky with someone they like more.
I've only ever had one gay clicky and that was the tower herald with his pink shirt and curly hair, even as a child me and my sister portrayed him as gay or at least very feminine. But while this was for laughs that clicky was just as much accepted as anyone else by us. Pretty much the same as how I portray him now in my stories.
We never did give him a partner though as far as I know, but as a kid I personly had little interest in playing out couple stuff.
But bottom line is that each clicky is a blank slate. Their name, personality, orientation and such is all for their overlord to decide.
