Post [Q][HELP][NOOB] firefox os

hello to all,
I have a couple of questions to ask those who know more than me about creations ROMs, etc. I am currently studying a way to make a light porting and running firefox os on my p990 ... I started looking at the work of JordanRulz ( I wanted to create my own version of the os. I wanted to ask, since firefox os is based on AOSP (if not mistaken) I can take the AOSP 4.4.2 and compile it with the latest version of firefox os? IF POSSIBLE, I would like some help and a guide to learn how to do it, and if I can prepare an initial version, also wanted to know where to turn to find out if I'm going in the right direction or not ...
thanks in advance to those who answer me =)
