Jim,
I'm no expert here but
your idea makes me nervous.  Better filtration may be unsafe.
That 5 micron filter will certainly make for less dirt in the system but it also will plug up easier.
If all the fuel has to go through it, make it the most reliable design.  This is one of those - single point failure items.

Subject: [LML] Legacy Fuel Filter / Gascolator

   Anyone have any good ideas for fuel filtration in the Legacy?  On my last one I used the Andair gascolator package, but was not happy with it.  The gascolator is nicely designed and manufactured, but provides only modest filtration.  The biggest problem is that when the gascolator is mounted in the factory-recommended location, it is almost impossible to reach during a usual pre-flight.  What's more, unless you have one person in the cockpit to bump the boost switch, normally almost nothing comes out of the drain when you try to get some with your fuel tester.  If you run the boost pump longer, you might run around quickly enough to get a little, but at risk of dumping fuel all over the ramp out of the cylinder drains and sniffle valve.
    I'm planning an even tighter cowl this time with Aero Chia's mods, so the Andair gascolator and drain system will be useless.  Thinking about using a Mallory 3160 racing style filter, with a removeable bowl and throwaway paper filter element, which provides 5 micron filtration.  Just have to catch any water in the fuel tank drains.
