Hey there, this is my first ever forum post. I like that you are taking feedback on your chosen names. smile
My full name is "Jaimee" which is common as a name (and I like it) but the spelling is sometimes unusual.
I just wanted to give you my opinion, as I have grown up with an odd spelling name, I will just say be wary of how many times your child will have to re-pronounce the name and/or spell it out every time someone writes it on a form, on an invitation, at school and in the workplace when they are older. I know my mum liked the spelling which is all fine, but it does get annoying having to see it wrong all the time, or you have to spell it out daily for people. Life would be much easier with a normal name! smile
Personally out of your above choices, Skylah is the best, at least you can read it in a list and don't have to sit there and stare at it and be scared you will say it incorrectly. smile It's a beautiful name. I agree with the MILO spelling over MYLO (again - a life time of correcting people).
Best of luck with your decision and I am sure they will suit the name you end up choosing. smile
