Your solution hardcodes logical influence as causal influence; these are quite different. Suppose your twin is a light-year away from you. Are you saying that your choice now exerts a causal influence over an event which is space-like separated from you?
You sound like you’re saying “you’re choosing what kind of agent you want (both agents) to be”; in that case, you’re looking at something more akin to Functional Decision Theory.
