Swap your dual crown fork for a single crown that will help give you a little more stand over height. I know people hate them but some short dudes will also switch to 24" rims. It won't look as nice but it will definitely help. The only other frame I know of that might be smaller then what you have is an x-small Giant frame. Hope this helps some.
a perfect bike for you sir would be a s or xs Rocky mtn Flatline... amazing standover, and it comes in XS... i.e. 5'2 inchs' fit the XS nicely... and the bike really does kick some ass.. so look into one of those frames nice bike
