Yes you can connect a site in a different site collection as long as it is in the same Web Application (your SharePoint time will know what I’m talking about). I’m pretty sure you can set it up to create automatically but you’ll want to test it. If not you can always add it manually through the SharePoint Sites setting. You should also be able to synch to it and make it work. There are two features that you need to active on your SharePoint site (or template) to get it to work. I don’t have the exact names off the top of my head but they start with Project Server…:-). Good luck.
