If you really want to continue this and you can't get the consent of the OP, then, to be safe, mold it into your own idea.

It'll a kind of renewal of it, but it won't be the exact same, you know? If you base your idea off of it, but don't completely take the entire thing, then it's okay. And by base it off of it, I mean create your own idea using the original as an inspiration and not a cut and dry copy, if you know what I mean. It's work for you, but if you really liked this idea, then that shouldn't matter.

Plus, if the plot can be generalized enough for you to safely create your own idea from it, then it won't be a problem. That'll take some analyzing and all that fun stuff until you hit the foundation, or at least garner a general concept from it, but it's the safest way to essentially 'revive' the RP.
