B&M rule question

[schwza]

i'm posting this here b/c i think you guys are the most likely to understand the question. supposed you're in a situation like this:

hero BB (8k)
SB (1 chip)
utg (1k)
button (1k)

button and utg fold, and the SB is already a-i. if you wanted to fold and preserve the bubble, could you? you couldn't do it online, but if you just winged your cards into the muck as soon as the button folded, what could they do about it?
