Provided that a local variable specified in a file is
customizable, does :set function of it called?

If so, I think the most natural solution is to change
  (defvar current-input-method ...)
to
  (defcustom current-input-method ...)
and provide a proper :set function (perhaps one that calls
activate-input-method).  Then a user can have this in his
file:
  
;; Local Variables:
;; current-input-method: "INPUT_METHOD_NAME"
;; End:
