The more, the merrier, I say!
I've never tried venison meat, so I have no idea how "gamey" it might taste compared to other ground meats, but if it's a flavor you like, I don't see why it wouldn't work. I will admit to preferring pork to beef, so if you're substituting one of them, I'd use pork and venison as opposed to beef and venison.
You'll have to let me know how you like them. Hope you enjoy!
