Your model just sounds more complicate and scrambled my brain. In essence, we are saying the same thing I believe. Where we differ is that you seem to be fine with the Trample function, whereas I, am not. And I understand abstracting a concept, but to make small targets attacked at the same accuracy of a larger target just seems counter intuitive. Why use fighters at all, if they can be targeted by a super capital ship just as well as a Battleship. You'd be silly to use up your Unit Cap with fighters (that in the description say are better suited for fighting Capital Ships) than with larger heavy hitting units.
