I wouldn't worry too much about archery hunters, they should know that there is a cow tag going on at the same time. Just make sure that you do everything by the book (tag your animal immediately, don't shoot from the road/across the road etc.) because you will probably be reported by someone who doesn't know about the hunt and thinks someone is poaching.
Go out next month and do some calling and see what you can get to come in. Last year I had cows on several occasions come in to bugles and cow calls within 100 yards. Too far for my skill level with a bow but a pretty easy shot with a rifle. Calling elk in is a great experience, give it a try if you can.
