Seeing as Namibia is on your list, I'm gonna suggest that you send a crew of park skiers down to Lesotho (a landlocked country, bordering only with South Africa) and shred up the park next summer.
The landscape down there is surreal - it will make you feel like you're skiing on Mars - and there are square peaks & strangely flattened, brown, dusty mountains in every direction. In the middle of this alien scene, an unusual white strip is blasted out of snow cannons during the coldest times of the year (May to September). One side of this thin piste of snow, which is shaped by a devoted team of South Africans & internationals, then becomes home to a surprisingly long line of features - Africa's only snowpark - "Kapoko Park".
Some of the features can be seen in this photo.
I spent several weeks working at the resort this summer, and it was an incredible experience. Skiing in full sunshine most days, with perfect snow conditions at over 3000m, this place deserves attention from a sport which is otherwise dominated by North American & European resorts. Not only is Lesotho the country with the highest minimum altitude in the world, the terrain also offers a varying expanse of riding opportunities when the snow does fall.
This year was also host to Quiksnow's 10th annual park competition, and although it was open to both skiers and snowboarders, the field was extremely oversaturated by our one-planked friends. The skier crew should balance that out when the time comes, next summer.

To add to all of that, the locals are friendly, living is cheap, and the mountains all around offer incredible opportunities. Send some crazy riders down there with their skis & zero expectations, and you will end up with killer footage of previously unknown territory.
