Cow hides in garden??

Hi permies (and sorry veganic growers) I have these two massive highland cow hides that are raw and stretched, but I never had enough time to scrape and start the tanning process. My garden this year was overcome with my failed winter rye cover crop experiment. I simply couldn’t terminate it. I tried rolling and crimping, weed whacking, and a twelve week tarping in the hot summer. I lost an entire year to this cover crop. l’m currently putting down cardboard and composted wood chips to hopefully cover and kill off the rye. My question is, has anyone heard of putting a hide down in a garden bed and covering it with wood chips or compost? the goal would be for it to decompose. The hides are about a half inch thick and have long hair. I’m kind okay with the hair persisting in the soil for a while. How badly could this go, and would it be worth a little experiment for science? I’m expecting quite a bit of no’s in the comments here, but if anyone would be open to a method like this, it would be permaculturists. Thanks!
