Seting up default content for a suite of websites

Greetings,

We are migrating our QuitLogix sites from V12 to V13 and have a wonderful opportunity to make some sweeping changes to how the original developer laid things out.

However I am now wondering if the way we are starting is the best, So I come to the experts to hopefully give me some insight.

We have a suite of sites that all use pretty much the same content with a few tweaks here and there, most of said tweaks are handled via Macros. With the current layout, each sites page would house a copy of the content and we would have to make changes if the default content would need to be changed, this would need to be done to some 30-60 sites.

Now my idea is to use resource strings to house default copies of the content (content templates if you will). The only issue I am running into here is that as the Localization has no Rich Text Editor, a normal editor may not be able to edit the content.

So am I on the right track here, or am I trying to use the Resource strings for something they were never meant to do?

If you would like to get an example of the scope, here are a few of the sites:
