Just my opinion:
If BO can be shown to be an Indoniaian Citizen at any time, would not the onus be on BO to prove otherwise. He can’t use the BC. He sure as hell will not declare he Naturalized(as you and others have explained. So the issue is not to get his BC. It is to prove he was an Indo citizen or even a Brit.
Given that both of his BC - the COLB and LFBC are frauds and not authentic Hawaii State issued documents they can do what they want with them - either in digital form or printed on a printer.
What that can not do with either is show them in court.
As for being a Brit. He has already claimed this. Indicating he was born a dual citizen. But since Kenya was not yet independent he was British - at birth. Assuming Obama was listed as the father at that time.
Many indicate Obama ‘lost’ his British status when Kenya became independent. But ‘losing’ British citizenship status or the right to claim British citizenship is almost never ‘lost’.
What is missing in this particular situation is another document. British government form RN.
RN is the formal renouncing of your British loyalty and citizenship. While looking for BCs and passports someone should try to find form RN. Without it Obama is still a loyal British subject I believe.
As a British subject he should be careful about what British military secrets he gives to the Russians and should probably give the Queen an upgraded IPOD.
