You have to graft to a closely related plant. Apple to pear, rose,
quince, and crabapple are possible. (My mother had three different
varieties of rose all grafted to the same apple stock.) Even apple to
loquat might work.

The best would be to an apple seedling. The seedling would unlikely
bear fruit similar to its parent but might have strong roots. This is
how apples are propagated for commercial orchards.

No, you cannot graft an apple to citrus or avocado. It just won't work.

Note also that less than half of the attempts to graft even the best
like-to-like actually succeed, except possibly for the most experienced
orchardists.
