You can do as you like really. We do already have the Green Knight whom I believe is connected to Sir Gawain in Arthurian legend. I don't want to speak for the others but It would be fine with me.

Yeah, the idea of the Green Knight started off with what I remember from reading Sir Gawain and the Green Knight.

Minus the part where he gets his head cut off, picks it up, and asks Sir Gawain to meet him in a year to receive an axe blow in return. ;)
