Hello! You can use the libraries of Spark with hardware of Spark LE?I think it's possible, but you have to remap your knob as the SparkLE does not have three knob per pad.
no remapping needed, because SparkLE still has those 3 per pad, only accessible 1 pad at-a-time, that is, those 3 knobs control the selected pad. Need to control another pad's 3 knobs? Select it, et voilá
oh, and yes, the libraries are the same since SparkLE owners will have the same software as Spark controller owners. Only the GUI skins change either according to the controller connected or by manually forcing one of the available skins, if you wish to.
