Sounds unnecessarily complicated. Many CVTs already "lock" in "top gear", giving no drivetrain losses when you're cruising.

The real killer for CVTs seems to be heat. When they're cruising in whatever final drive they've got, they don't build up much heat. When you're accelerating or hill climbing, they do.

A more important modification for a CVT would seem to be an auxiliary oil cooler. That's what Subaru added to the WRX for the CVT... and it's a necessity! CVTs on other turbo Subarus seem prone to heatsoak and reduced performance during spirited driving.
