You may try using FrameMaker's Apply Master Pages function (7.0 or later) for this purpose, as follows:

-- create a new master page, named LeftRegular (or something similar), that will control the layout of the standard Left pages

-- modify your standard Left master page so that it become the special blank page ("intentionally left blank" or so)

-- in the mapping table controlling the assignment of master pages based on paragraph tags or element names, specify that "Body" paragraphs (and/or any other tags encountered on regular body pages) on left-hand pages assign the LeftRegular master page

As you use the Apply Master Pages function (which may be document- or book-wide), the reserved "Left" master page -- not applied by any other paragraph -- will then be the "blank" page.

When switching to the Apply Master Pages approach to control application of custom master pages, all assignments should be controlled through the mapping table (as manually assigned master pages are reset); test the master page assignments you need in a complex document, including multi-page tables (if this applies to your documents).
