A...The boss wanted to add a late shift tomorrow, but he was short one person so he had to abandon that idea.
B...Really? No one said anything to me about that. I could have worked late tomorrow.
In this case, can I replace "could have worked" with "will/ would/must have worked late tomorrow"? Please.

If I don't go now, the train will have left.
I will have worked late tomorrow.
If the second sentence is not acceptable, why the first "will have left" can mean a future action, the second "will have worked...." cannot? Please.
I could have worked late tomorrow.
I will have worked late tomorrow. this sentence has no meaning.
The first is "could" which is right, while the second is "will" which is wrong. Why? Please.
Could: possibility from an objective point of view, presumptive.
Would: implies desire and intention; certainty
Will: suggests stronger certainty and desire than would and absoluteness.
Must: must+have+done sth only refers to things in the past.
In the original conversation, the second person comments on their boss's decision to give up the idea of adding a shift which, if happen, would probably see this person "work late tomorrow". In this context of talking about something external occuring in future, "will" is the first one you should cross out. Hence you can only replace could here with would. Personally I think even would sounds too intentional and certain here. Strictly speaking, could is irreplaceable here to me.

What's meaning of 'external occuring in future'? Please.
