No, he wants two characters WHITE CHESS KNIGHT and WHITE CHESS KNIGHT ON
DARK BACKGROUND, and a variation selector, say VS2, that when applied to
them yields a glyph that works with block elements.

It might be simpler if WHITE CHESS KNIGHT ON DARK BACKGROUND was
defined as a character that worked with block elements.

No, WHITE CHESS KNIGHT should continue to fulfil that role.  My only
worry is that one might need a variation selector, say VS1, to force the
choice of a suitable glyph.
