Never tried one. Not really my thing, but it does look like you might have issues with keeping the Stella mirrors and mounting that. Stella mirrors mount using a metal bracket below where that windshield mounts at the same spot. But it's hard to tell if the metal bracket for the stock mirrors moves the mirror stalks out far enough in front of the windshield to clear as the stalks come up.
But I'm sure you can easily manufacture a longer bracket that moves them out far enough to clear. I made a small bracket to go below those brackets which I use to mount my koso Harley tachometer on my handlebars so that it doesn't contact the handlebars and is angled just enough to be easy to view while riding.
In fact I hate how the stock mirrors are not wide enough to effectively use. They tend to get blocked by my wide shoulders. I ended up buying longer stem mirrors to counteract that but those are cheaper chroming and rusting already when the stock ones have no rust. So I might just make my own brackets that allow me to mount the original mirrors slightly wider so they aren't blocked by my shoulders!
I have the same issue with mirrors and not being able to see, I put on a sports seat that sits lower and that helped. I'm not a big guy at 5'9" 170 lbs.
Thinking about investigating if I can swap mirror brackets left to right and mount on inside of headset.
Thought about leg shield mirrors more than once, it's just not natural to look down to see behind you.
