I actually had something close to that in mind, to be completely honest - but just wanted to ask the original maker of the plot, before proceeding to tweak it around. 

However, I do like that idea, mainly because (as you mentioned) it gives another emotional layer to it all. And after adding a few more details to the plot, it could be a really good premise in my opinion :3

The only other thing that my heart misses here is just a good ol' plot twist and I'm happy.
