Makes sense to me.
Of course, what would also be worth considering would be an enhanced rig manager (dare I use the 'editor' word??).
That way, you could have FX chains for the footswitch set up an a no-nonsense browser on the PC and easily assign performances and then just pop your custom FX chain on there as you see fit.
I know there will be replies saying that it's easy to do on the Kemper itself but I don't agree. My only gripes with the unit have always been lack of editor, lack of spring reverb, more delays and the ability to put reverbs / delays before the stack if you want. I know for sure that, since Rig manager came out, that is what I always use at home to browse rigs. It's just so much easier and the next stage should be a decent editor with the ability to see exactly what's going on with performance slots and fx chains just makes so much sense.
When I use my DAW, I use custom FX chains all the time and it makes life a lot easier. On the Kemper, the ability to have 'your chain for blues' and 'your chain for metal' or whatever would be great. Just dump it on a profile and you are done, both on the performance and on the footswitch.
