I actually made Olympia to be a strong female that way. I don't know much about Starfire in the comics but I have heard unfavorable stuff. I just don't want too many pure physically based characters in general, if everyone had durability, regen, and strength It'd get boring. 

Well you can just say it's a form of pure magic energy from her home plane that ties all of her powers together and has unique properties. I've never played D&D so I can't really comment :P 

I'm not really familiar with the metric system being a Yank but aren't kilos, kilograms? Hmm. Well I just don't want her to be like Maxwell as an unstoppable powerhouse. I'm thinking she should max out at a ton or two to keep everything balanced. Plus that's like gorilla strength and everyone knows gorillas are awesome. 

But the changes are good enough for me to accept the characters just gotta get the cosmetics for their birthplace and stuff like that. Making up a name for a magical world might be fun :P 

And from now on let's try to tone down on the amount of physical characters.
