You need not worry. I'm playing singleplayer with a modded Coalesced that resets my ammo everytime I reload, but it only effects singleplayer, not multiplayer (Cause those lines are in diffirent sections).
EA/BioWare/Origin will not ban you for cheating in SinglePlayer since it doesn't harm anyone else.
They will ban you for cheating in Multiplayer cause that can upset the balance or give you an unfair advantage towards others.
Is it even possible to gain any tactical advantage in MP by modding coalesced?
Well my guess is that you could be able to make buffs such as Adrenaline or Cloak last indiffinatly or give certain classes other abilities (like giving the Engineer Singularity).
