replacing all the computers with my colleagues

I have now discussed the proposals for replacing all the computers with my colleagues. I have now discussed with my colleagues the proposals for replacing all the computers. With my colleagues, I have now discussed the proposals for replacing all the computers. The first sentence is fully misleading. And in my view, the second one seems a little cluttered because it puts my colleagues and the proposals, the two NP, together. I am not really into this expression. I think the last one is the right way to express the original and right meaning. Which is the best way to express the original meaning for native speakers?
