The thread on status challenges here has been dead since 2021 (you can search for it) but in any case I cannot recall anyone reporting that Marriott has granted a request of the type you mention. Soft landings also appear to be a thing of the past so you cannot even look forward to Platinum as a consolation next year. Having said that, your spend is quite high for 37 nights so you're clearly a higher-end customer and it never hurts to ask however I think your difficulty will be having your request land in the inbox of someone empowered and caring enough to action it. The only certainty you'll get is to jam your stays into the early months of next year while you're still Titanium and reach 50 nights as quickly as possible thereby giving you decent status through 2023 and 2024.
