Maybe you can try something like the following?
(defvar python--font-lock-keywords ...)
(defvar python-font-lock-keywords
'(python--apply-font-lock))
(defun python--apply-font-lock (limit)
(while (< (point) limit)
(let ((next-boundary (find-next-boundary limit)))
(if (we-should-skip-this-block)
(goto-char next-boundary)
(let ((font-lock-keywords python--font-lock-keywords))
(font-lock-ensure (point) limit))))))
