I'm introducing one of my toys which has a simple setup - nominated in MapVote as a mutator in chain - not Run-Line or whatever RULES.
This is not removing DMMutator but it might be speaking with it toward replacements. Then internal handler can make player to fire weapons (not TournamentWeapons) On-Line or it is passing job to XC_Enginev16+ if can be found.
I was testing it in MapVote (LA type) using BotPack.CTFGame and Level CTF-Niven (that one with GesBioRifle and Eightball and whatever Armor) which is using to get screwed by DMMutator but not a lot when we are loading this stupid thing.
Also if player picks up such an old item, is possible to see that BIG WHITE PickupMessage at Bottom of screen like for BotPack items. Actually this tool works even as server-side and does 0 replacements. Also I was testing it in server running "UnrealShare.DeathMatchGame" - that old DM - voted.
This is not a Must Have.
This can be changed if it sounds bad ( because has source-code there ).
This can be modified if do works annoying.
And so on...
