Would it be worthwhile to have the dial redone to what it's supposed to be? I think it would be cool.
Not worthwhile in any financial way, but if you would enjoy doing it, there's no harm in trying, except for wasting your money.
Personally, I wouldn't even consider doing that, and here's why. (1) It won't be easy to know how it is "supposed" to look, the best you can do will be to find a legit example of that general reference. (2) Even if you find a legit dial to emulate, it will be virtually impossible to have the dial repainted well. I can't refer you to anyone that I'd consider to be competent to do a good job. Quite honestly, I have never seen a repainted dial that I would be happy with, and I have seen thousands. You could easily spend hundreds, and still end up with something just as bad, or worse. And (3) even if you miraculously manage to have it repainted well, it's still a repainted watch, with no value, no history, and no ability to inspire joy.
In your place, I'd prefer to spend my time, energy, and money finding original examples.
