That is likely to be quite a bit more expensive and probably less accurate after assembly.
I think the design is sound. Let's let it play out. The bearings should never move from the v rail. The v rail will keep them in place. One wheel cannot wander on it's own. If anything moves it would be the gantry, but the wheels on the other side should prevent that. The wheels may slip during assembly, but should be fine after that if everything is lined up.
When I quoted the linear bearing system, I had the company that makes the dual v bearings quote bearings with a molded in place Delrin v wheels. They quoted them for $2 each ($2,000 min buy though). I think that is the ultimate solution.
