A few things -
Hands are designed to fit a specific movement. That said, they often require a bit of broaching (with a small, round file-type of tool) to increase the diameter of a hand's opening. Definitely, work that is best left to a pro & not something I would recommend you do until/unless you have a good bit of practice.
As to the dial itself, I have seen better & worse. I am also 1 of the few here that do not like dials that have been heavily modded because they look 'artificial'. About all that works (for me) is a light coat of shellac or a few minutes in a 350 degree oven - both procedures have very fine dividing lines between art & damage, so practice 1st &/or proceed with GREAT caution.
Unfortunately, there is no easy way to reverse modifications done to a painted dial short of replacement. So if YOU are dissatisfied with the result, you may need to consider a replacement. Again, dial mods/refinishing is not a task for the unskilled.
