Hi alphonse55. I know your post is years old, but I just wanted to let you know that I have the same problem. I just moved into a house in Bend, OR, and the original late '90s Moen shower handles stick out about 1.25 inches. I replaced the whole shebang—cartridge, handle, cover plate—in one bathroom and the new one sticks out as well. Seems the original contractor didn't put the valve back far enough. In this house the only way to fix it would be to open a wall and redo the valve or replace the fiberglass tub and put in drywall and tiles.
The reason I'm writing, however, is that I believe there could be a fix. All we need is a thicker cover plate, one that covers the distance between the shower wall and the faucet handle. Maybe we could modify old hubcaps?

Anyway, Moen should make some sort of wall cover adapter to bring the cover closer to the handles in installations like ours. I'm going to call them to see if it's a possibility.
