Would it really? All you would be doing, is in effect, highlighting large chunks of text and hitting the delete key. That wouldn't take much time at all. And as for swearing, all you need is the Word (other word processors are available) 'find and replace' feature to put in an offending word and replace it with something less offensive, hit find and replace for whole document and in less than a minute, job done...
Yes, it would, because there is often important dialogue embedded, and some scenes advance character development or story development, and would need to be re-crafted to not lose the development while eliminating the graphic details. Some graphic details are embedded into dialogue that is not a specific sex scene as well.
As for editing, I use BBEdit on my Mac, which has extensive search features (including regular expressions) and can search my 12,000,000 word corpus in less than 1s for straight text, and less than 2s for basic regex. π
The other thing that it would do is likely require adjusting chapter breaks so that chapters are generally in the range of 5500 to 6500 words. Transition changes would be necessary as well.
It's not trivial for the 4,000,000 words that comprise 'Good Medicine' alone.
