I've found an m2 exporter but it only works with version 2.4.2, you can export these with MyWarcraftStudio, go to open mpq archive > select common-2.mpq > browse for character>blood elf> then select male folder and right click it> export folder and compress it on a "zip" or "rar" file.
I need it so I can go on my project on custom playable characters, and maybe ill make a guide on it.
Thanks in advance.
