Yeah, sorry. Dan is correct. There is some basic physics involved here.
Most of the best features from E switches come from the rapid signaling thats possible with a dedicated signal path. Without it, power must be cut, have time to drain from the circuit and flow back in before the driver can see it as a signal. This is why second mode is easier to reach LMH than HML. So things like double clicks are generally impossible to do well. Especially at high power levels that take more time to drain.
It may be easier to design a new light with an E switch for implementing the features you are after.
