I think your post-blue application should work fine. I took a cheesemaking course a couple years ago (which is what got me hooked on making cheese) and one trick we were told was to go buy a cheap edam or mild cheddar, and take our favorite blue, smear some over the cheap cheese, poking holes in it, etc, then wrap with foil, put in the veggie crisper, and leave it for a month or two. Then, we would end up with a kilo of blue cheese. I've not tried it myself, but someone on the board did and it worked fairly well for them. So, with your far superior cheese, this should be a star! A cheese to you for trying yet another approach.
