I doubt it. At least nothing "reliable" ie that will last more than a few months. Its a matter of energy density. IE you just need more material which takes more space.

If I ever manage to nab a second 6700 cheap I plan to see about putting the 1800 mah extended pack (with bump) into the phone without the bump.

The extended pack sticks exactly 1/4 inch out the back of the phone. SO I would need to find 1/4 inch of space and at least 1-1.5 mm of spae for the stock back cover. I could live with a 1mm bump. SO if I distend the back of the stock cover AND thin it by a mm all I have to do is get rid of 1/4 inch.

Question is how think is the two sides of the battery skin and how thick is the phone case skin below the battery (anyone got phone taken apart who can measure the thickness of the plastic below the battery?

When I have some extra cash I will buy another extended battery and sacrifice it to see whats inside.
