You can pick up a pretty good quality road bike for a few hundred quid these days (Boardman, Specialized, Giant, Decathlon, etc). Saves getting rid of the mtb. As for SWMBO, surely you earn your own cash, and spend it how you like?
I’m facing the same decision on my road bike. You won’t be able to stop thinking about the new stem until you buy it and fit it. When fitted you will feel better and you will also like your bike more, and ride it more!
