People add, remove, and replace substrate all the time. As long as your substrate doesn't leach anything into the tank, and you take your time so you don't smother a shrimp, I wouldn't see any issues with it. I'd watch your parameters for a bit afterwards just in case it causes a mini cycle, but other than that go for it.
You shouldn't take life to seriously. You'll never get out alive.
