What is Centerline for Aimpoint Twist Mount with Spacer?

I have an Aimpoint M4 mounted in a Larue LT-659 tall mount (centerline 1.725") and want to use in conjunction with an Aimpoint 3xMag in a twist mount.

Is this possible? I don’t even think the Aimpoint 10566 Spacer would bring the 3xMag high enough.

Thoughts?

(I’ve already tried the Larue LT-649 pivot mount)
