I think that I've found my answer, but I will like a confirmation that it's the good way before I do it.

- create the Historical League,
- Export the stats at the game setup menu,
- erase the false stats in the 3 files created,
- Import the 3 changes files in the game.

Just to be sure an example :

Hank Aaron played his first major league season in 1954, so to have his real career stats in my league I've to delete those lines :
