Eric, I'm in much the same boat as you. I have a 2015 Verve 3, and I have bar ends on it that are similar to the Profile Design ones. Truth, they were on an old MTB that I bought for parts, and I swapped the bar ends to my Verve. I scored a similar set in anodized silver color for my Trek 750 of the local List of Craig for 5 bucks.
I like the outer ones for the same purpose as you -- to mount mirrors. Yes, the grips do need to slide in a bit to accomodate them, but with the handlebar as wide as it is already, I find that an acceptable compromise. I've tried to like road bikes, but I just don't like how narrow the bar usually is (40-50cm). My hybrid bars are in the 58-62cm range, and I'd go even wider if I were buying a replacement bar.
