I love
Gwen,
Gwendolen (this spelling) and
Guinevere and I think
Gwen is lovely either as a nickname for
Gwendolen or on its own; it feels complete, warm and lovely. For me,
Gwen feels less intuitive as a nickname for
Guinevere so I'd probably go with something like "
Winnie" or "
Vera" that *sounds* closer to
Guinevere, or even "
Gigi", going off of the first letter. I made a bunch of combos for
Gwen quite a while back but I don't have access to them right now. How about...
