Copying an existing group with the same ACLs does not make sense to me.I would opt for automating this approach, as often it does not stay with these few dozen groups, especially when you need to make changes. With automation it's much easier to be sure that you have processed all groups and applied...

Then it depends how your content structure looks like. Assuming that  www.abc.com/sample is rewritten into /content/abc/xyz/test.sample.html, then I hope that you have a path /content/abc/xyz/test in your repository; everything else would make this situation much more complex. So in that case invali...

What do you mean with "these pages do not exist in AEM"? How do you get them created then?

I understand that you want to take existing data and embed it in a flexible way in existing components (using placeholders?).  Something similar to Contextual Content Variables (CCVar) of ACS AEM Commons [1]? [1] https://adobe-consulting-services.github....

of course you can do that, but I think the benefit is large, especially because you don't need to rewrite all tests at once. But you can start with using the Sling Mocks / AEM Mocks when you need to create tests.To your case: You probably need to mock each single step:@Mock Bundle myBundle; @test v...
