I think the idea that is being missed is this:
Your combs will be drawn by younger house bees than field bees. Regardless where combs are placed, they will always be drawn by the same group/age of wax yielding house bees.
Frame placement in the hive does not impact cell size. What does impact it is the number of regressions that the house bees that are drawing comb have successed through.
What forward frame placement "could" do is prevent (or at least make them feel uncomfortable) in placing stores in freshly drawn (regressed) comb. This "push" of old combs to the rear is a good idea as you said, because older/larger combs will become the stores frames and be easier to extract.
Also consider that the placement of old broodframes with foundationless - starter strip frames will force regression. House bees will have to draw comb to have any area to rear brood.
This is a dangerous fall endeavor but your idea was to do this in the spring, I'd not be so worried that my brood stock would dwindle in the spring as it might if this process was done in the fall.
Also keep in mind a small degree of regression occures with each broad hatch, cells diminish in diameter with larva cocoons. Used cells are eventually re-built when the diameter becomes unacceptable, but regressed bee have a smaller "acceptable" diameter than unregressed bees too.
This "dirty regression" if you will, is not as effective as starting a new shook swarm regression or systematic frame replacement. The bees do have a range of acceptable comb diameter. Newly hatched and regressed bee will have a smaller cell expectation than older unregressed bees. And the point that I am trying to make here is if you have a hive that is under the direction of older bees, a larger cell could be acceptable whereas the shook swarm will result in younger direction where only a smaller diameter will be acceptable.
At some point the used cells become too small for the queen to properly lay. I guess I have found a new question that I'll post in a new topic:
Do queen bees evolve to lay eggs that hatch with regessive tendancies or are workers regressed by their crampt cell size alone?
Is it a product of both?
There is always more than one way to skin a cat, that's of course if you're into eating cats.
