Name Change??

Okay...I'd love anyone's advice (only if you agree with me HA!  Although I really don't know what I think...sigh).  We've got quite the discussion going on over here about "changing" Karleigh's name.  I have always loved the name Caroline, and thought for years that if I were going to adopt, I would name her Caroline and call her Carlie.  My other two girls names are Katherine (Katie) and Alexandra (Lexie) and so Caroline (Carlie) would follow the "girl name rules" that I had planned.  Here comes the challenge for me.  For those that do not know, my husband's name is Karl.  That is Karl with a "K".  He is also a Jr. and so as a kid he was called "Karlie" (shhhhhhh!).  My problem is is that I like the name Caroline spelled with a "C"...but not Carlie.  Karoline with a "K" is growing on me...especially since it's a feminine form of "Karl".  But what about the spelling "Karleigh" that we have fallen in love with!?  Oh my....What a tangled web we've weaved!  I'd love to hear anyone's thoughts!!!
