Nickname for a character

One of my characters is named Circe. She has two main nicknames, Circe-dircy, and Circ. They make sense the way I read them, but what I want to know is if you were reading this and you know her real name is Circe, how would you pronounce her nicknames?
The way I pronounce them is dircy rhymes Circe, Circ is just Circe without the 'e' so it ends in an 's' sound. Is there any other way you'd recommend me spelling/writing them?
Thanks

I tend to read unfamiliar words phonetically (mixing French and English phonics sometimes, heh) so without seeing your explanation, I pronounced "Circ" like "Cirque" as in "Cirque Du Sole" (French for Circus of the Sun). So I guess they pronunciation way would be "sirk." (And that is right from a French/English dictionary)

Once I looked at how to pronounce "Circe" and just dropped the "e" I was fine though.

Well, I pronounced 'Circe' like Sears, but with the 'c' sound instead of the s. So, I just kept the 'e' silent. I'm not too crazy about Cirece-Dircy as a nickname, mainly because 'dircy' doesn't mean anything-- it's just a rhyming word --and they're spelled differently although they supposedly sound alike. Circ is good; I pronounced it like Rosey, as in 'Circle' but without the 'uhl'.
