Is it possible to place pages from one InDesign file into another less the master page data from the source file?

You’re welcome. I had to test this to make sure, although I was pretty sure it would work. You can turn layers on and off in Illustrator files, Photoshop files, and PDFs. Why should INDD be any different? I almost always put master page items on their own layer, usually because I might want a background image below page numbers or headers/footers. This is just one more reason.

But you create now 2 documents unrelated to each other. You do not know what the OP intends to do (even that I would bet OP would just like to get rid of the headers and footers).

I’ve done that multiple times having different headers/footers but the same document and content. Create the document once, use multiple times.

I’ve also used different layers to include the different headers/footers. You switch on the layer you need and export. Both methods have merits and disadvantages.

In one case, we produced panels, that some wanted not only to display, but also distribute as paper copies, but instead only the e-mail in the footer, having the full address. In addition the different formats where in different sizes (but close enought). We have one design (the panel design). For the other design (the print designj, we just place, scale to size an add the address. Easy to maintain data consistancy.
