I'm building a Cozy, which as you all know has a landing brake. 
This would drop down right in front of the radiator. Obviously, 
for times when you need a landing brake your engine cooling requirements 
ought to be fairly minimal, but would the radiator get enough air in those cases?

No but I don't think you would need much cooling on final approach.

To flip that coin around, would it be possible to simply arrange for
 an adjustable-angle radiator to have a much larger adjustment angle 
possible? 

If you can get the hose to flex that much or  build a sealed rotating
coupling. 

In that case, it would create a hell of a lot of drag, and 
it would seem to provide as much or more effect as the landing brake 
itself. In that case, if you don't need the landing brake, you get the 
parts/weight reduction as an added benefit. (The downside is that 
controlling the radiator angle doesn't sound like something you do 
with a simple push/pull cable. What do you envision for a control 
mechanism in a pusher configuration? I can't quite envision what 
this might look like to produce a strong, stable, and reliable control.)

I think you would need an electric linear servo as the forces would
be quite high. McMaster Carr sells em.
