That would be an extremely short sighted move (which has obviously never stopped major corporations before).

One of the major problems from the last writers strike was that no WGA member (which often included show runners) could be on site for filming or make script adjustments. This means that frequently actors need to do their own rewrites which are often of questionable quality, and they don't like to do (since it's essentially being a scab). I think producers can also do rewrites, but I'm not sure they'd be much better at it.

One of the primary reasons Quantum of Solace was such a rough movie is Daniel Craig was doing rewrites himself in the evenings since it was filmed during the strike.

The obvious solution would be to do everything in their power to follow the script to the letter but oftentimes it can't be avoided. Some lines might not land the way they read on paper, and some sets cannot accommodate action the way it was initially scripted. All of these would require script rework.

All this to say that as long as the WGA strike is going, almost anything being filmed will be of notably lower quality.

As I pointed out at the start, this may not be enough of an incentive for studio heads to relent and pay their writers a living wage; but it'll certainly hurt the bottom line soon enough.
