That would be very poor English. The construction would probably still match what is in the answer shown above: "Ik ben niet heel populair". As a native English speaker I can think of no occasion to say "I am very not..." the not or negation would always be before the other describing adverb. "I am not too fast" (never "I am too not fast") ... "She was not very excited" (never: "She was very not excited") .. Hope that helps. .
