What could a Revive of LoR look like

With 2XKO entering cryostasis, it has gotten me thinking about Runeterra's current time of being mostly on ice.

Since it stopped being updated I have always wondered if this is LoR's final fate or if it could become more active again. Path of Champions never left but I always liked the PvP portion of the game, and would love some of the PoC specific content like Fiddlesticks to make the jump.

What would you want to see from LoR getting a second life, and would you be hopeful or pessimistic of the success of a revival like that?

Also, can Riot solve the issue of this game making money?
