Yes I think it's tricky.
Matching lume wouldn't be a big problem

There are many tricks to get the right matching lume (mix color or take a cigarette and hold it under the lume to get it darker or brown)
I'm not a friend of wrong parts on a watch and go on hunt to find the parts.
I have this problem with my speedmaster and it's a never ending story or very expensive.
it's another story if you get a good price and you can live with it and you find fast the right hand.
In this case I would pass this one but that's my opinion.
