I think you're over-complicating the situation. I have a couple of ropes in throw bags which have pre-tied bights in the rigging ends and stopper knots in the other ends attached to the bottom of each bag. I often untie and retie the bights after use and when cleaning the ropes, and I also switch ends in the bag sporadically. But I don't think it would be a big deal to leave knots permanently tied either, if you choose to.
To further complicate this discussion, I seldom rig to the bights that are tied in my ropes. Confused? I put the bight in there in case I need to clip-and-go with the rope in a hurry. But most times I rig with the spare rope left at the TOP of the drop, not in a useless heap at the bottom waiting for somebody to grind it into the mud or drop rocks on it. I usually rig the system to be releasable under load if necessary, using a locked Munter hitch, Tensionless hitch, or similar. Something you might want to consider.
I'm not sure why Kuzgun replied about joining ropes, because I don't see any mention of that in your original post. For what it's worth the Double Fisherman's bend he mentioned is a standard for joining ropes, but it can be quite difficult to untie after loading. There are other more rigger-friendly options.
