Victor, as Wim says, the lighter weight dollies will work. The bottom board is narrow, you might have to bore your own holes in the dolly so they come up in a convenient place on the piano. I through-bolt dollies to the bottom boards. You have to check ahead to make sure you clear the trap work.
You are correct the dollies will raise the pedals quite a bit as the cabinet was designed to essentially be resting on the floor.
Another option is to attach 'outriggers' to the sides of the piano. You would have more control over the pedal elevation.

Thank s Chris,
Your piano has casters, mine does not and has a little more space but I will take a closer look next time I see it.
Best,
Victor

Victor,
I just did a dolly installation on a Yamaha U1 last week. The U1 I worked on was an older model without the front legs, and it's pretty similar to the P2 in your photo.
Like Wim says, the dolly wheels sit outboard of the bottom footprint of the actual piano. I thought like you that the dollies would make the piano unstable, but those worries turned out to be unfounded.
The dollies do not come with screws, which is a real nuisance. I happened to have some #12 wood screws lying around (1.5 inches long) that worked out perfectly in the end.
