Radar Mount on Thunder jet Chinook 3/4 hard top

I'm installing radar on my boat this year and just received a Garmin 18 xHD radar dome. My plan is to mount it directly on top of the 3/4 hardtop, no mount bracket but I will place a 1" board (say star board) to give it a bit of a standoff so I can bring the wiring through the roof and seal it properly and add a bit more structure to it.

I've seen one similar mount (see attached image of blue thunder jet) its a full hardtop and mounted forward, so it should work. But just to be certain I have few questions for boat owners with a similar setup.

The roof on the thunder jet slopes forward already, so I'm not doing a wedge, do you see any issues?
Mounting the radar more to the rear (see image with red lines) will that be an issue, even with the two rocket launchers?

Thanks for any help.
