Just start simple, maybe adapt a tried and true formula, like a board game, but you know, with an actual interactive component. Gmod Murder adapted clue for videogames, maybe you could do that. Or maybe make a VR SCP game, like Secret Laboratory. Or if you wanted to go with a singleplayer story tell one that is infrequently told, such as the operations conducted by Weatherman in the 60s, or the siege of the Waco, Texas compound, or put the player in the shoes of the Unibomber, or the Iranian embassy incident. The first and third of those could have some very cool bomb-making gameplay similar to the tenseness of the bomb-defusing in Keep Talking and Nobody Explodes.

Still though I think it would be simplest and safest to adapt a winning format to VR, like Mafia. Starting small with a clear goal in mind should also allow you to set a time-based goal, thereby eliminating the possibility of "no work to show for time spent."
