I believe that layers came out with either Adobe 6 or 7. You might want to Google "layered PDF" and see which programs that also create PDF support layers. If they support layers, they are going to have a merge command. Any program that allows you to make layers of anything is going to have a merge layers command.
With respect to Adobe, see if you can't find the earliest version that supported layers. You can very likely get a screaming good deal for it on ebay or other online sources since they are now up to version 9.
I don't know if any of the free or el cheepo PDF creators out there support layers. I've been using Acrobat Pro for a loooong time, so I'm a little out of the loop as to what other programs can do.
