Even if possible, why would one need to do that? that's a waste of solvent.
EDIT: And you'll get heavy base (lye) contamination in your end yield. (if possible)
But that's not possible, because lye is polar and doesn't dissolve in non-polar solvents, so it will simply drop at the bottom of the dish, in solid form, and doesn't react with the spice salts to turn them into freebase, blah blah blah
not possible
