You don't even need to.

56% of all matches are 2-2-2.
18% of matches are either 1-2-3 or 2-1-3.
Only 20% of matches has a higher Duelist count than 2 with 1-3-2.
That means in 74% of matches Duelists are either just 2 or lower per match in numbers, with Strategists 18% of the time being 3 in number out of that chunk.

Duelists are not significantly more picked than the other roles, nor do we actually need more Duelists at this stage.
Vanguard is the role that really needs more heroes, while there only being 9 Strategists in the game.
A double Duelist season is absolutely insane, every single season should have at least 1 Strategist or Vanguard.
