Yeah, you can handle all of that through the workflow and Set Revision tools.You can move the AutoCAD file through the workflow to an Obsolete state to lock it out from anyone using it. Then the SolidWorks drawing can utilize Set Revision to get to the current Revision value since you'll be somewhere down the line in Revision values.
PDM is a file management tool. you can make references from one file to another, but each will have separate and distinct "histories", since drawing1.dwg is a different file than drawing1.slddrw. therefore the solidworks files will NOT be the next version of the autocad file in the eyes of PDM.
(there is a hack to make it be the next version of the original file in the history, but I won't detail it here as it has far to sever drawbacks).
