IIUC all this seems to be fluidsynth bound. Multiple soundfonts are 
stacked by engine, and the last loaded one takes precedence over the 
same bank/programs. Thats why you cannot assign one bank/program from a 
previously loaded soundfont to a channel if some later soundfont is 
loaded which implements the same bank/program number pair.

I believe there's help with the bank-offset thingie, but I can't tell 
you much more as I don't grasp it very well ;)

Have you tried to name and save your channel layouts as presets?
