RE:New Page Replacing Expired Page with Same URL
Could you please describe the issue on more details? What error are you getting?
Right now, I would use workflows and versioning for this. You will have just one document (however, I do not know whether you want to use also different layout and design or only content). You will create version A, set it to be published until date X and move it to publish workflow step. Now, you will create version B, set it to be published from time X+1s and again move it to published workflow step.
