Thinking about the possibilities a bit more, you might want to have a look at this post by Chris Kenniburg. Read it carefully as he is discussing some ideas in different parts that might influence how you can achieve a good outcome here. Also, his boss, Troy Patterson, has some interesting things to say on some management issues. Not suggesting you adopt them, but they could help inform any discussion you and your colleagues may have on a longer term strategy for your Moodle. Good luck.
