League of Legends MMO

So is it just me or does the passive team comps for TFT look like they could be converted into classes for a League style MMO. Like Assassins would be rouge like class. Knights (tank/shield), Brawlers (damage/tank), and Blade masters ( straight hard sword damage) would be trees that you could go down under a warrior like class. Elementalist would be hard cc/aoe mages and sorcerer would be more straight damage mage. Elementalist could have three trees (fire, ice, and either nature or blood). Sorcerer would have (arcane (ahri/veigar), nature (nidale), and void magic). The races could be human, yordel, void, darkin, and Vastaya race. The range classes would be gunslinger (more ranged cleave damage and could dual weild), and ranger (more long range hard damage). This is all really basic classes, but if they were going to make an MMO now is the time since they basically have the building blocks for it now. :what you think any opinions.
