Is it possible to turn MXML into as3?

Hello Dear Members!

I wonder if it is possible to turn all mxml files into as3 and then into hx completely and without any issue ? so that we can get rid of the mxml extension.

Second question is is it possible to get rid of MX packages? I mean all files under mx folder in my project are in as3 extension. So if I convert them into hx extension it means that I can use them in my haxe project?
