Not exactly.  As I understand it, #become involves references changing
from one object to another.  I'm thinking of something more like:

   module M
   end

   a = Object.new
   class << a
     ancestors.unshift(M)  # essentially same as a.extend(M)
   end

I'm not sure how that would matter specifically.  What problem are you
envisioning?  (Not that the whole thing wouldn't be a train-wreck
anyway :-)
