OK didn't read if anyone else said this and this is honestly the first thing that popped in my head. Don't know how practical it sounds, however, a *perfect* FQ bundle to me would be a "make your own" type.
If a shop online or brick offers FQ's why not let the customer customize their own choices and price could be what's determined based on the number they choose to include. I like bundles but I don't always like all the fabs in it so it's not economical to me since I won't use them all.
