my take on national recruiting is that the primary benefit would be for top players to attract multiple top schools. this competition among top schools would "open things up" a bit for everyone else.
however, as recruit generation is implemented today, i don't see that happening with any scheme. i think there need to be a crop of elite players. in bball today, there are often freshman among the top handful of players in the country. in HD, its never even close. so i just don't see there being any player good enough to justify a bunch of guys going after him.
also, i think a combination of national and regional recruiting would be the ideal situation. the star system originally proposed kind of rubs me the wrong way, partially because it is such a poor measure of talent. but, i don't think it should cost more to recruit a 1 star than a 3 star on its own, that should only arise out of competition IMO. i would prefer a solution where the say top 25 players nationally are all recruited at a 250 mile distance, so everyone can go at it for those players, but lower prestige schools who have no shot at those players still have their backyard advantage.
anyway, with the "close to home" and "far from home" feature in the game today, we might already have most of what we are looking for. according to lostmyth's FAQ, he puts far from home at a whopping 50-75% advantage. in the single battle i've analyzed with that as a component, it seemed to make a very significant difference. at least, the number i have trusted for so long didn't even get me close to the actual outcome. it made 0 sense unless either 1) everything i know is wrong or 2) far from home is quite significant. at 50% that would be enough to open a recruit up to national recruiting, i think. maybe not the guys over 1400 or whatever that upper cutoff is that puts campus visits up to 2K, but I think it negates the distance advantage for everyone within 1400 or whatever.
