You could animate the offsets and spreads to zero and then transition from
zero to the other shadow type. Theoretically. :) But it probably makes more
sense to not allow it. The author could animate two shadows if they want
that kind of transition:

   box-shadow: 0 0 127px rgb(0,0,254), 0 0 rgb(254,0,0);
to
   box shadow: 0 0 rgb(0,0,254), 0 0 127px rgb(254,0,0);
