Since High Detail Decals tend to make GZDOOM Crawl, I havent seen any gore mods of that kind so far.
But, there are some games that have detailed decals which you could replace manually on certain mods, for example
Turok 2 Seeds of Evil Remaster by NightDive has some hi-res Decals on its files, but since its a commercial game I wouldnt touch it
for distribution, only for personal use.
