Rogue One Galen Orso, Saboteur? (possible spoiler)

Okay, so we know that Jyn Orso's father was involved with the construction of the Death Star. And we know he probably was forced to do it, since he was the one who sent a message out to the Rebels warning them of the Empire's super weapon.

So, is it possible that Galen Orso was the one responsible for the ventilation shaft that went straight to the core of the Death Star? I bet he helped design it underhandedly for the purpose of then telling the Rebels and giving them the ability to take down the battle station.
