We can't schedule a vote so quickly as members need lots of notice, and we need a BUIP to vote on first, which has had some time for review and comment.
I think it is reasonable to say that the BU elected officers have authority to maintain the funds in the Bitcoin fork with the most PoW chain. That can't include a spike when difficulty is too low due to EDA, but it can include a sustained period of >50% hash-power when the new DAA is operational.
So it needs a BUIP to override and make an early decision to move some percentage to Cash, but once 50% is hit after the DAA then the officers should switch the holding.
