Would you probably have an overall better image and experience if you got some taller rings that were better aligned? Yeah, probably.

Will it most likely still work, even if it's not optimal? Unless you're needing 100% absolute, unimpeachable precision, also probably yes.

I do not know the exact specs of that particular clip-on off top of my head, nor am I certain that the action rail is the same height as the barrel rail, however most I² clip-ons generally tend to be optimized for right around the 1.4"-1.54" optical range, close to what many would consider "absolute cowitness" (nevermind that cowitness with a magnified optic is pretty iffy...) or "High," or close to it for most traditional rifle rings.

The biggest issues you will run into is potentially exacerbated POI shift due to the curved lens coupled with edge distortion in the tube, as well as reduced light collection (meaning reduced performance envelope, i.e., "how dark" you can go and still get a usable image) due to the offset / "losing" some light from the tube. Again, I am not familiar with that particular model of Vortex, however in many cases what you'll find is that the true discriminator between "higher end" and "lower end" scopes is often low light performance / light collection. It's not really particularly hard to make a scope look good on a bright, sunny day, which sometimes leads people to wonder what exactly they could possible be gaining with a more expensive scope, however, when the light begins to fail, and/or you're needing to resolve an image in very dark conditions is when many lower cost scopes may start to drop off more drastically and more rapidly than a "higher end" scope.

That being said, again, I've seen a lot of folks use mismatched height optics, including plenty of military folks, and I've done it myself from time to time out of expediency, so the reality is, under most conditions, it will probably work "okay," because most of us, even the TNVC crew, are not usually operating at the extreme ends of performance and capabilities limitations--that's why it's an extreme, it's just that that "extreme end" may creep up on you a little faster than expected or maybe outside the window of suiting your needs.

Unless there is a reason that you absolutely, positively do not want to remove the scope, my thought would be that the better investment would be to just go ahead and swap out with some higher rings, especially given that it looks like you've got an adjustable comb there, and go ahead and try to get the most out of the equipment you've got.
