Should I get a solid tire for just the rear wheel?

I want to get solid tires as I'm sick of replacing the tubes, but I also worry about the comfort of the ride.

My idea I came up with now is to just replace the back tire with a solid tire and keeping the front an air filled.

My mind set is that, 1, most of the compression that happens when I hit a bump or pit mostly falls onto that front tire and not as much on the back. (Idk if that true, I assume so). 2, I've had to replace my rear tire where the motor is maybe 7 times and the front once. 3, the rear tire is a pain since it's got the motor there, while the front is easy since it can be detached.

Is this a solid plan?
