I think about 12 cm can still be chiseled away in total width without having to change the lintel. Yes, a fixed element is probably sufficient there (bei Kontrollierte-Wohnraumlüftung). Unfortunately, aluminum is only equivalent in this regard. You can still gain height: without openability, the threshold is not necessary at this point in my opinion.
