How much should international stats count towards a MLB career?

As any of you who read this blog regularly may know, I think Julio Franco should be considered for the Hall of Fame.

If you count his 3 years of international ball he has over 3000 hits and, for a number of years, did that as a SS.   But somewhere in his career he decided to go for the money and played overseas, presumably because he couldn't get a MLB contract or, at least, one that he thought was reasonable.   I don't actually know as I don't know the man but, for whatever reason, he spent 3 years playing in the Far East.

While he had only 2586 MLB hits, if you add the 442 he had in Korea and Japan he totals out to 3028 hits in individual country's idea of what major league baseball is.

So, in the days when recent players (Alan Trammell) who failed to get enough votes anytime in their eligibility to elected to the HOF are actually still getting in, I think it is time to consider Franco.

In thinking about Franco the case of Ichiro Suzuki comes up.  Hey, the guy is a HOFer for sure as he got to 3000 hits even though he spent some of his productive 20s years in Japan.   So, the question with him is not whether he makes the HOF, it is  (a) is he a first time HOFer and (b)whether he holds the record for most hits in a career.

Right now Suzuki has 4514 hits between his time in the US and Japanese major leagues with 3080 of those coming in US major league.   By contrast, Pete Rose had 4256 hits, all in the US major leagues.  even if you discount the quality of play in Japan to some degree, it is very possible that if Suzuki had played his entire career in the US that he could have and probably would have eclipsed 4256.

The question is, is there any multiplier we can incorporate into OUS stats to determine what that player would have had based on his age, ability, history of MLB  performance and state of baseball at the time when he played abroad?  In this age of advanced statistics I think this has to be possible.  Also, maybe all of our stats records should have a series of records for career stats for guys who have combined US and international careers.

Why is this important to me?

(a) I think Julio Franco deserves to be in the HOF

and

(b) Ichiro Suzuki deserves to be a first ballot HOFer.
