As you state the problem, it is not possible, for the reason that you
have explained.

You could do it with a macro:
@linemacro indexfn {entry}
@findex \entry\
@cindex \entry\
@end linemacro
Then instead of writing this:
@findex foo
- you write this:
@indexfn foo
That will put the "foo" index entry into both indices, with a single line
in the Texinfo source.
