As long as you are planning never to sell or insure the watch & do not mind causing raised eyebrows among those in-the-know, you can paint the lume in a dayglo color like red to match your wife's fingernail polish. But reluming a valuable vintage Rolex, especially with modern lume, seriously deflates the watch's value & makes a nice gen look questionable. As I have said elsewhere, I am all for refurbing a seriously worn out vintage piece, but some things really should be left as-is (or, if refurbed, as they should be).
