even though the whole 'aim down your RDS with nightvision' is retarded 95% of the time.
You're stuck on old paradigms.
Passive use of RDS through head mounted NV has been a TTP for quite some time now for many of the exact reasons you are now thinking of trying it to the point that it is now the preferred method for some professional users.
If you want to try it as a "proof of concept" before investing in a dedicated mount like the KAC Skyscraper, you can simply get a cheap Picatinny riser from CTD or Amazon to try out and see how the added height works for you:

...though it's not something I would particularly rely on for hard use or retain zero.
You could also go with a slightly more expensive riser from Wilcox, KAC, LaRue, Leupold, Hahn, etc. that would be more "duty grade" without being requiring you to buy another mount, especially one that is exclusive to the Aimpoint Micro pattern--the whole KAC Skyscraper/Redback One mount grew out of Jason Falla using a lower 1/3 cowitness mount on a LaRue 5/8" riser.
Just for reference, a quick chart of mount/riser combination heights:
Absolute cowitness mount = ~1.54"
Lower 1/3 mount = ~1.7"
To clear an AN/PEQ-2 or 15 = ~1.93"
.410” riser + Absolute cowitness mount = ~1.95”
.410” riser + Lower 1/3 mount = ~2.15”
1/2” riser + ABS mount = ~2.04”
1/2” riser + L1/3 mount = ~2.2”
5/8” riser (or HK416 upper + .410” riser) + ABS mount = ~2.17”
5/8” riser + L1/3 mount (or KAC Skyscraper mount) = ~2.33”
3/4” riser + ABS mount = ~2.29”
3/4” riser + L1/3 mount = ~2.46”
(height measurement is from the top of the rail to the centerline of the optic)
