I am not sure what your concern is about replacing V brake wheels is. Wheels are pretty robust these days, not prone to failure. And if your concern is specific to the rims on wheels that use rim brakes, I have no such concerns. All of my bikes have rim brakes except one has a disc on back and rim brake on front.
I do see a slight improvement in braking in wet conditions with disc brake compared to rim brake, but that is the only significant difference that I see.
But it is your bike, not mine, do what you want.
