Alliance are a serie of different mods. On the Star Wars GC, you can play the civil war Empire vs Rebel era + Black Sun and soon the Republic and CIS.
I have added a new style of turrets for the turbolaser from some staships as the Allegiance. Another changes are a few improves with the ion guns from the Allegiance.
Are you have lighter version of your mod in plans? I know, you want include everything, but 70% of units not using (ex. i can build Defender cruiser from clone wars for 4500 and Mandator II for 12000. And what will be my chose?). It's just my opinion, but maybe it will be useful.
I have plans but I can not give you a date, perhaps even it will not be for EAW and it will be for Vol'Takes.
But build or not build, the full version has a lot of different GC and you can not build everything at all them, there are many units but they are limited by the era.
