I wouldn't try to design this from scratch; rather, I would look for some stock rubber or foam extrusions a bit larger than the door gap. Refrigeration and automotive suppliers might be good sources, or even McMaster-Carr. If Doorman chimes in, he might have some specific suggestions. (But don't go for the LynDoor® "Universi-Gasket." One size doesn't necessarily fit all.)

After many hours of hard work, LynDoor™ Industries has recently developed the Octi-seal Doorjamber® sealing system that uses multiple suction cups to ensure an air tight seal between doors and the ambulance/work truck body, up to speeds of almost 13 miles per hour.
Look for it soon at your local ambulance/work truck door seal supplier.
In general I agree with Tornado, why try to invent the wheel again?
However, there are circumstances where you need a different wheel. This link takes you to a list of cars with unusual doors. I can only believe each of these has some unique gasket or seal requirement that required engineering.
Can you tell or show us more of your needs? I also agree with the others that the overwhelming assortment of products from LynDoor™ Industries should be reviewed.
There is more to your request than you have told us.
There is a company called Soft-Seal that manufacturers replacement door gaskets for classic cars. They could help guide you to find what you want. The common gasket material used on the compartment doors of ambulances is roughly the shape of an "L", but with the angle between the vertical and horizontal at about 45 degrees. Because the doors are usually made from 3/16" aluminum, and flat, the usual method of attaching the gasket to the door is to just glue it on.
Some times the weatherstrip will just be flat foam gaskets, also glued.
With roll up doors becoming so popular, gaskets are changing. A lip seal on the bottom of the door, and a pair of lip seals along the sides of the door frame.
Nice posting. The weatherstrip you have shown would be more effective, if you were to eliminate the flat section of the weatherstrip,furthest away from the hinge, and make the remainder of the weatherstrip thicker, and allow it to intrude into the interior more. It will be better at conforming to the inevitable irregularities encountered. Another option would be to use a D shaped weatherstrip, in place of the triangle. The triangle is going to be forced to crush more on the flat side than the slopped side. That might not be good for long term sealing. I don't see it being done in the production world.
