Done. Thanks to Curns for the info/instructions and TAfirehawk for the mini-modcomp 
CustomTraits:
Aggressive:
as per AggWithStables, see below.
Expansive:
+2 health
+50% faster settler production
+100% faster Granary production
+100% faster Harbour production
Industrious:
+50% faster worker production
+50% faster wonder production
+100% faster Forge production
Imperialistic:
+100% Great General emergence
+25% faster production for melee, gunpowder units
I'm looking for other possible changes to Imp (instead of +25% faster production for melee, gunpowder units):
+25% faster production for mounted, navy units
+25% faster production for seige units
+25% faster production for seige, navy units
free City Raider promotion for seige units
--------------------------
AggWithStables:
This one doesn't have the CustomTrait changes. It is for those who may want to try Aggressive with Stables out in a normal game. The Mongol Ger has had its cost increased for balance (much like the Zulu UB).
Aggressive:
free Combat I for melee, gunpowder
+100% faster Barracks production
+100% faster Stables production
+100% faster Drydock prodution
Mongol Ger costs 70 hammers.
