This question is... ???
Just based on if the people are into casual sex or poly or whatever, who the hell knows? This is like a little kid saying, "A tiger has stripes and a leopard has spots. Would they get along?" I mean, they're both cats, right?
But so many more factors are important to relationships, that no one here can say whether or not this pairing "sounds like" it would work.
Is there a more specific reason or issue that you want addressed?
The world opens up... when you do.
