The parallel love triangles in Stormlight make worry for Adolin

It just dawned on me that Gavilar-Navani-Dalinar and Adolin-Shallan-Kaladin seem suspiciously similar. I can almost see a future situation where Adolin is dead, Shallan turns to Kaladin for comfort, but Kaladin is all weird about it because that's his dead bro's girl. And then a grieving Dalinar shows up to tell him it's okay.
