I suspect the bounce test could work to a certain degree, by this I mean there probably would be a correlation, but it might never be verified. Even with a very simple bouncing test, there is still a lot of variables to control.

We all know hysteresis is the major factor influencing rolling resistance, but I suspect hysteresis in a rolling tire is different than from a bouncing one as hysteresis changes with the speed of the loading-unloading cycle, which may be analog, but is different between a rolling and a bouncing tire.

Crr is such a complex principle, not only does it changes with every tire size, it also changes at every speed it is tested...
