First, changing to a larger diameter wheel doesn't do much for the steady state rolling resistance. The change in tire size has very little affect. So unless the change makes a different set of tires available to you, I wouldn't go there.
But what about the non-steady state - the acceleration and braking? It depends on the weight. Some wheels may be lighter - that would be advantageous. But what's important is the inertia - and the polar moment of inertia at that - something you can't measure without specialized equipment.
Other should chime in, but I am of the opinion that this is NOT an avenue that is advantageous.
- BUT -
If you can increase the diameter of the tire, that might be advantageous - and you might not need to change wheels to get there.
