how would you spell/pronounce Khephry?

I want to say “Keff-rey” like [name_m]Jeffrey[/name_m] with a K. And I quite like that, Khephry, but I’m trying to figure out how you could spell it so it maybe was easier to figure out. And not just spell it as [name_m]Jeffrey[/name_m] with a K.

Maybe:

Kefrie
Kephrie
Keffrie

Keoffrey
Kefrey
Kefree

I think Keffrie and Keoffrey are the most usable.

I really like the sound of it. If it’s for a girl:

Kephrie
Kephrey
Kefree
Kefreigh

Boys:
Kephrey
Keffrey (I do like this spelling)
Keoffrey
