Is it possible to overload the “as” or “is” operators

Question

Is this allowed? If not, can this be accomplished inherently by overloading the implicit/explicit conversion operators?

Answer 1

Is overloading the "is" and "as" operators allowed?

No.

If not, can this be accomplished inherently by overloading the implicit/explicit conversion operators?

No. The "as" and "is" operators tell you what a thing really is. They pay no attention to user-defined conversions.
