You could mount the radar on an pedestal mount. That will get the radar up and over anything. Check out SeaView's website for some examples. I've even seen some where the pedestal comes with an integrated mounting plate for the spotlight, as well.
But, I agree with others about the glare when mounting a spotlight on a hardtop. You can put a shield under the spotlight, but in my experience, it's never good enough.
Without moving the radar, you could mount the spotlight at the bow, as mentioned. Either along with your LED light, or in place of.
Another option... scrap the remote spotlight idea and install LED lights on either side of the hardtop. I would think they would be thin enough not to cause an issue - or maybe mount them at the edge/under the hardtop. If needed, put an extra spacer under your wedge.
