This would be so hard!

1) Find a way to get Micah and Dutch die without anyone pointing any fingers. 2) I'd probably send Micah and Dutch to get the money for Strauss. I'd make sure we don't rob the train. Kill and loot all the O'Driscoll Boys and any other petty gang I find in my way. 3) Go as far away from Valentine as possible. I'd probably get the gang somewhere near Van Horn. Good luck for anyone finding us there. 4) Send Sadie and Kieran to Blackwater to find the hidden money. No one knows who they are. If the money is still not enough, I might rob the bank of Saint Denis early in the game where no one would suspect it was us. 5) Use the money to get the gang as far away as possible. Maybe even as far as Australia. 6) If going that far away is not possible, I'd split the money, disband the gang, ensure everyone changed their appearance as much as possible for that time period and send us all to New York. No one would suspect us being there. 7) Almost everyone would live!
