levy, there's really no such thing as 'wasted foam'. Your not getting jipped if one foot needs less foam (volume) than the other. A foam liner with a foam tongue and a zip fit are roughly the same price @around $400.00. Two pairs of different thickness intuitions will coast about the same.
As a rule of thumb for someone putting in a lot of days and mileage, you fit the small foot and modify the shell on the large foot. This is not uncommon for folks with sognificant assymetries demanding a high performance fit. In my own case, I fit my left foot in a 27-27.5 shell. There's relatively little work that needs to be done on this one other than a small sixth toe punch. The right foot though is a bit of a project: navicular, 6th toe, styloid, pushing out the toe box and removing s bit of material, and some grinding in the heal.
This is a discussion to have with your fitter. Honestly, you're obsessing. The best solution to you obsession IMHO assuming your fitter did a good job would be to suck it up and do a foam liner when your stock liners are toast. There's no such thing as wasted foam in the higher volume foot, but if you want to hold on to that notion, it all equals out as your small foot gets more.
