There is never a cure for missing a delivery timing requirement. It's a violation plain and simple but some disclosures still have to be delivered but in doing so it does not negate the timing violation.
IMO, if you don't issue the revised GFE within the 3 business days then you are bound by all the fees disclosed on the original GFE and if you are found to have issued the GFE after the 3 day requirement and you adjusted the fees based on the revised GFE you could possibly be required by your regulator to adjust the closing fees on the SS to the original GFE figures and refund accordingly. However, since I have not seen any exam procedures this is purely speculation.
