I tinkered with it on my laptop with ableton and M4Live on a plane last night. Not back home to actually try it on kemper till new years day but seemed to be as simple as going into editing mode in M4Live and changing the table's range attributes but adding values (each separated by spaces) all the way up to 125 (which is the max number of Perf slots in the KPA). Now when I have go into ableton with your device assigned to a midi track i can raise the PerformanceSelect Envelope all the way to 125. So presumably it should work, and it looks to be sending messages out. The table in the instrument only increased to 64 slots instead of the full 125---might be some M4L limit or i just need to figure out what attribute i need to change to increase it. But since my need is really for working in the Sessions view its not really an issue for me. (Of course the larger table size meant I needed to resize some things and rearrange your device layout a bit. But it is still essentially "your look"! 
Again, a great little routine---VERY useful for Kemper users who are performing live with tracks on ableton and want to be free of the footswitch tap dance and just play!
(Oh, one other thing, just going through this editing experience i learned so much about Max---the bug has bitten me hard!)
