New (maybe) Mechanic Idea

Hello!

Would it be possible/interesting to have a game mode where you could turn in your cards mid turn?  I have not thought this through, but it seems like there could be some interesting outcomes with this option.

I am assuming you are saying, don't cash up front (only possible with 3 or 4 cards), then at some point (likely depending on how well an attack goes), you cash to finish an objective?
