Is it possible that CFB change the genesis account of all the people who have pledged  for the deal, they can send him a pm, then sign with their btc adress from presale, the btc received from the deal will be sent to this btc adress.

I am just thinking that it is better than only promises of pledging....but it will consume time of CBF... So I don't know

For reminder I am pledging 100K IOTA for the deal.
