Can you also include the other missing stats like.
No I cannot.
costUse cannot modify any stats, it can modify only resources. And it is already possible to modify all 6 resources.
current TU, energy, current HP, stun, morale and mana are not stats, they are resources.
max TU (pool), stamina, max HP (pool), bravery, (max) mana pool, firing/throwing/melee accuracy, strength, and so on... are not resources, they are stats.
