Low ammo only addon - Brutal Doom mod for Doom

I have found that brutal doom gives the player too much ammunition, reducing much worry. So, I took ProfessorExistential's mod, and edited so that it just reduces ammo in general. Originally, his mod added gameplay balances and a reduction of ammo pickups, but I took out the gameplay balances, and reduced the ammo capacity for cell and some automatic weapons, while keeping the reduced ammo pickups. Speaking of which, I'm trying to also reduce the amount of ammo the player receives when picking up dropped ammunition. If anyone one can tell me something, that would be great.

If you want to mod this, go ahead! Do whatever you want with this, I don't care. This isn't really my mod in the first place.
