A different 2wd low range mod

I know the standard 2wd low mod manipulates the input to the 4wd ecu from the a.d.d. actuator. Has anyone tried to do the same thing with the transfer case actuator? There may be some nice advantages to doing a transfer case 2wd low mod, like direct on-the-fly switching between 4wd low and 2wd low. Doing this would also enable the use of the rear e-locker, if you have on, in 4wd high range.
