I'd say this could potentially be worth a new thread, with how much it has evolved!
Consolidation
For intuitive design, I'd suggest that consolidation is based off of the consolidating model's position rather than the model they removed from the table. Prone models or No model (in the event that they rolled an OOA result on the injury dice) makes it hard to do the kind of measuring in the document.
Making it based off of the charging model's position means you have a consistent point of reference.
Yes, an enemy model is safe if 3" behind their buddy, but with clever maneuvering (or removing the need to move in a direct line) there is some fun interaction there.
Vaulting Barricades (Initiative Test)
It may prove best, to save on constant rolls, to have there be one initiative test to ignore barricades rather than one for each. So if your model is trying to hurdle an obstacle, they make the test. If successful, they ignore it and any others for the duration of the turn.
Wording
Some tightening of wording, such as for "Knock(Basic)" would be good. "Knock(Basic)" implies you can choose to either remove Scarce or add Plentiful, which is not clearly an act of upgrading the ammo "rarity" of a weapon.
