Galen didn’t construct the DS, only the laser.
Then how did he construct a convenient way for the rebels to destroy it???
That’s a common misconception. He didn’t. All he did was make an unstable reactor to set off the chain reaction. That’s why he wanted the rebels to steal the plans, so they could figure out on their own how to set it off. He didn’t have a clue how the rebels would do it. It’s entirely possible he was expecting an espionage mission than a bunch of snub fighters trying to make a one in a million shot.
So it would have been possible for, say, a 4 person crew to infiltrate the Death Star and sabotage the faulty reactor using the Death Star plans carried by R2? It’s a good thing there was never the chance for such a sabotage mission or the Rebellion wouldn’t have needed to give away the position of its base and send almost all of its fighters to their destruction.

I don’t know, and Galen didn’t either. According to the novelization, it’s implied that Galen signed off on the exhaust port design, but it was confirmed by Lucasfilm recently that he did not design them.
Besides, I doubt Luke and Co. were well equipped to perform such an activity, nevermind knew that was an option. After all, that’d require them to open up the plans (which they can’t just do, it seems like), they’d have to recognize the faulty reactor (And Galen would not just label “Hey, this reactor’s set to blow” on the plans, unlike “Tractor beam power switch”), and then they’d have to deliver a strong enough shock from a remote enough distance (as I doubt anyone but Leia or Ben would be willing to embark on a suicide mission, and one person is not a sufficient force against overwhelming odds, though the force may balance it out).
And that’s assuming it were possible. Neither Galen or myself know what the complete technical readout of that station looks like, so it’s entirely possible that wasn’t an option.
