Hope you manage to do that!
As it is all data, and I've even seen/heard people using excel to edit the game, there must be lots of things that can be scraped and used.
Some time ago I submitted an idea to get more historical facts from the savegame. Like the career top goalscorers for all teams that I managed, the club that I bought most players from, or the manager that won the most matches vs my teams, etc Somewhere deep down FM is counting all those things, but we only see the current record holders, or sometimes the one in your current team that is the best right now, but not the players that are at the 2nd/3rd place and beyond. My idea is under review, but I don't know how long such a thing takes, or if they consider making it available. But somewhere inside our savegames all this information is already there. As all players have ID's and those ID's can be shown ingame and in third party tools, I think it is possible.
