Peeta + Katniss = Pee-Niss

Or kat-ta

or kat-pee

would katniss and gale be kale?

I think they're called Everlark.

Katpiss

No they would be toast.
Boy with the bread + Girl on fire = Toast

Well, with Ship names, the guy's name comes first. So the answer to the original question, is yes.

It's either peeniss or katpee so they're straight out of options
