There is the
Ankit/Gambo v4.0 database that does what you are looking for. If I am correct, this database works as you like for players making their debut after 1960. Although I haven't checked specifically, Brian Holman would import in his pro-debut ('83/'84) rather than 1988 when he made his major league debut. You seem to be aware of the requirement for fictional players if you wish to have a full system of minors but do know that this database is not a work-around for that issue.
