"weapon reskin" mod?

is there any weapon mod that has no (or maybe slight) change in gameplay whatsoever? The only one I know is Eriguns. but the guns in that mod is buffed up a little (rip english)

Smooth Doom and its variations; Doom Delta are probably what you are looking for.

If it's just the stock weapons: https://forum.zdoom.org/viewtopic.php?f=43&t=32628
