Bassed exclusively in civ bonuses, which civ is better for hussites?

UTs, UUs, Arquitecture and techs can be changed, so civ bonuses are what I'm interested in. Also team bonuses that would really help them (I'll figure out a way to introduce the civ/civs through the campaign so they feel natural). I am thinking of giving Hussites only feudal units and rams (data mod so archers look like xbows) + mercenaries (FM, Condos, Genoese Crossbowman, Dismounted Konnik and Janissaries) and their strength (War Wagons, HC and BBC). I was thinking of Sicilians so War Wagons can tank pikes, but gunpowder civs look tempting. Just for the record, they'll get full upgrades on infantry and archers as well as a good bunch of UTs to make them unstoppable. I don't know by now how to create units but once I do I have a rather long list. First real war wagons (Serjeant armour in melee and pierce, tanky as fuck and with organ gun attack damage and animation with bonus against cav)
