I completely re-profiled my Marshall JCM2000 DSL100 and got, IMO, 5 really good, usable profiles that are raw and in your face....the way a hot rodded Marshall should be!
You can download them from my site at: http://richardantonelli.com/kemper-stuff
I'll eventually get around to adding these to the exchange as well. Please let me know how these work out for you!
