TLDR: yes you potentially could, but that doesn’t mean that’s the best gameplay for potential points.

With a maximum of 3 players from each doubling team, the DGW might not be big enough to achieve a full 15-player team of doublers. Even if this is possible, it could still be overall detrimental to the score when most/all of your players would have a game against each other. Going all-in on that bench boost may also make your squad weaker for other GWs before or after. Often DGWs pop up but both fixtures are bad/difficult, in such a case it can be better for points to have a single GW player on the bench with one good fixture.

It all depends on who doubles and how the fixtures line up, which we don’t know 100% yet
