`query-replace' is not invoked from Isearch.
`isearch-query-replace' is invoked from Isearch.
So your wish is about invoking `query-replace'
instead of `isearch-query-replace' from Isearch.

Your wish is not different from other similar desires e.g.:
"I want `M-e' in Isearch to exit Isearch and call `forward-sentence'
instead of editing the search string" or "I want `C-y' in Isearch
to exit Isearch and call `yank' instead of pulling string from the kill ring
into the search string" and the same can be said for other Isearch
keybindings too.

All of them could be solved at once by implementing a new feature
that will bypass Isearch keybindings to original commands.
