What if I use two relays, one that is NO and one that is NC, and I use the RC circuit to delay the opening of the second circuit? So, no power would go to the NC relay unless triggered by the NO relay through an insulated rail activation.

I think you mean something like this. I would look into an NTC resistor for the delay. It would slow down the turn on of K2.
