Yes: an after-advice. On `font-lock-fontify-syntactically-region`.
Something along the lines of
(add-advice 'font-lock-fontify-syntactically-region :after
#'my-font-lock-comment-to-cursor-sensor)
(defun my-font-lock-comment-to-cursor-sensor (start end &rest _)
(save-excursion
(goto-char start)
(while (< (point) end)
(if (not (eq (get-text-property (point) 'face)
'font-lock-comment-face))
(goto-char (or (text-property-any (point) end 'face
'font-lock-comment-face)
end))
(let ((s (point)))
(goto-char (or (text-property-not-all (point) end 'face
'font-lock-comment-face)
end))
(put-text-property s (point) 'cursor-sensor-functions
#'my-cursor-sensor-fun))))))
