The way to do that in D is with mixins:
That is an interesting solution.
However, my original goal was to figure out whether one can make
struct types behave polymorphically (Which is not mentioned in my
original question). I know that this is not supported by design.
I want to keep the original struct types but also allow functions
to accept those struct types and do runtime dispatch. The
following code should give a better idea by what I mean by this.

The user need only define Duck1, Duck2 ... with appropriate
functions and mixin toDuck. Then a function that accepts a Duck
can accept DuckLike (for dynamic dispatch) or templatize on the
type of Duck.
