This is what I do.
One channel for loud and one channel for quiet at about 40 db pad.
Since you are not about play back audio to anyone at a 140 db dynamic
range anyway you can handle it in edit.
Use the quiet until you distort and then mix in the padded loud stuff
and cut out the quiet channel when needed. Everything used from the
loud channel will be close to 0 db when working with thunder. The end
result is not noticed. When mixed correct you can still bounce the
people off their chairs at 96 db and they can still hear the
intercloud and echos at -80 db below that.
