Nissan Patrol 4x4 (Africa)

Has anyone seen this type of conversion done or a COTS product?

I am looking at converting to 35 inch wheels on the Patrol, and from what I could see online, the 35 spare won't fit on the back door anymore.

The option is there to install it on an aftermarket rear bumper. But I don't mind putting the spare on the roof rack and then using that space for kids bikes.

I simply built an angle iron bracket (more of a spacer, really!) to move the spare wheel carrier slightly higher & further away from the door...
