Ex-England union internationals Danny Cipriani, Billy Twelvetrees and Tom Youngs, and league players Keith Senior, Adrian Morley and Danny McGuire, are among those taking part in the match.
It will include unlimited tackles in your own half but six after halfway, uncontested scrums and line-outs, with five points awarded for a try, and two each for a conversion and a drop-goal.
Gale, who retired from playing at the end of the 2024 season after helping Wakefield to the Championship title, is looking forward to the challenge.
“I’m coaching the Wakefield academy now so I might jump in with their session later to crisp up my skills,” the 36-year-old said.
“I’m a big fan of Cipriani. I think he could have been a gun in rugby league because he has a rarely seen skillset. I’m excited to go up against him.”
He added: “It’s win at all costs. It’ll be good craic but as soon as we play a game, it could be chess or tiddlywinks, winning is the name of the game.”
