Answer:
No, this is is not allowed. Lender "error", "oversight", or whatever you choose to call this is never an "out" to call for a revised GFE. Page17 of the April 2, 2010 HUD FAQs, states "None of the information collected by the loan originator prior to issuing the GFE may later become the basis for a "changed circumstance" upon which a loan originator may offer a revised GFE, unless the loan originator can demonstrate that there was a change in the particular information or that it was inaccurate, or that the loan originator did not rely on that particular information in issuing the GFE."
