Any way to gas charge the back of the seal to press harder over the hump?
Maybe with that, you wouldn't need any springs at all!

I think it already works that way.
Unfortunately when the seal passes over the hump the pressure in the 
trailing combustion chamber is not much as it has not yet fired.
The inward acceleration is proportional to the RPM squared so
at 7000 RPM it is twice as high as it is at 5000 RPM.
