HELP! Will hen sense different timing of replaced eggs?

[PoultryPedia]

I have a hen who went broody on 13 banty eggs I didn't want hatched. I have replaced them two days ago with 5 large fowl eggs I had developing in the incubator, and am thinking of adding in another 5 eggs (The hen's a determined broody so would likely tolerate that).
Question--The replacement LF eggs are a week and a half further along than original eggs were, and are due to hatch Saturday morning. Will hen instinctively know not to be turning the eggs now?
Thanks for any help!

Time's getting short for action. Any knowledge anyone can contribute?
Also, do you think heat and moisture loss under hen while I inserted additional eggs would be significant enough to cause problems for eggs?
Thanks again!
