I don't see any of y'all, except maybe JW, considering what really happens. At least in my experience with mixed fleet local racing.

I ran Slip to Ship for five years. In that five years there were anything from 40 to 60 boats. Of all sorts, and I mean all sorts.

Here's a breakdown:
I'd have two or three 6.0na, one of whom carried a chute and had a famous USSailing admin as a crew;
two to three 18sq, one of whom is a Cat I;
four to eight H16, three-five TheMightyHobie18 (not enough numbers to justify busting them out for their own trophy);
One or two P18 'classic' both of whom have oversized Smyth sails that we nicknamed 'P18mx';
One guy had a 5.8na with widened beam and 6.0na sailplan, and he even singlehanded this thing;
One N6.0 Express;
One or two Inter 18;
Two to three Inter 20/Nacra 20, one of whom has an aftermarket main;
Hobie 18 SX, one with chute, one without;
One, maybe two, Mystère 4.3 (with chute but high rating, ouch, yeah, I caught a buttload of **** for ya, JW)
etc, there's more, but y'all get the idea.

Now, I'm running this race with effectively two people who know anything about Portsmouth scoring. Any volunteers I can get prolly don't know what in Hell is going on with Portsmouth (Isn't that a city in Rhode Island?) So they don't know what to ask when they're handed entry sheets with incorrect, or as usually the case, NO Portsmouth rating.

Asking some of these modified racer guys to know what their rating is? Y'all gotta be FUCKIN' kidding. Yeah, they should, but they won't...

Asking the WAY understaffed RC to MEASURE? Y'all gotta be FUCKIN' kidding!

In my experience running Slip to Ship, Joe Average Racer has gone and bought some new sails for his old boat that he's fixing up, mainly because he CANNOT AFFORD to shill for something newer. Joe wants to go out and be competitive with what he has. Joe don't wanna bother with all that scoring crap, that's what he paid the entry fee for, the RC to handle it.

ANYTHING that y'all yayas contemplate to change the system better damned well consider what I suspect is usually the case, a harassed, understaffed, fried out RC who just wants to put on a fun race with a minimum of bitching. Do I sound burned out? I hope I do. I PROMISE y'all that the declining number of regattas and participation will only continue to decline if y'all come up with a system which is even more RC-intensive than Portsmouth is.

Personally, it's been my observation that Portsmouth is just fine. Like I said before, the fast guys win. I've never seen it happen any differently in my five years of managing S2S. Chances are, the people who aren't happy with their numbers are the ones who don't bother understanding the ratings system or learning how to sail well.

Whatever system is implemented should absolutely be NATIONAL or INTERNATIONAL. Local weather or whatever anomaly is "averaged out" and any bias applies to ALL boats when the sample size is large enough (ergo national/international). Local handicapping is an extremely bad idea for local political reasons. Local measurement is a bad idea for the same reasons, and also because on a local level there isn't enough manpower.
