I would tend to disagree - if they're small and moving fast, they get a dodge score. Their hull should be their hull strength, not some wishy-washy combination of the two.
Giving a fighter ludicrously high hull and then throwing in ludicrously high dodge smacks of giving them double for their money - less dice are likely to hit it in the first instance. And even less of them are likely to actually make it past their evasive action.
What you're effectively saying is that for any given weapon system, a 25m long fighter with 25mm armour plating (or whatever) is just as tough to slice in half as a 25million tonne battlecruiser, with plating 10m thick.
And the fighter has a dodge score, too!
