As others have said, no. What nobody seems to have said yet is why. If
Y descends from X, you are saying that Y is an X; that a Y can be used
anywhere an X can. If Y doesn't support some methods of X then it is
*not* an X, and *can't* be used anywhere an X can.

Rather than looking at workarounds, as others have, I think you need
to go back to your design and work out what's gone wrong that you
/want/ to descend Y from X. Your present design is wrong, plain and
simple. Working around it won't fix that.
