I don't have one, but just some food for thought.
Most cutter-grind folks are pretty skilled. If you send them the die, they will either inspect it, or CerroSafe the die and back into the reamer dimensions, much like they do with sample cases or unknown chambers.
Unless you are grinding that reamer yourself, maybe have that conversation with your reamer folks and see what they say.
I find it strange that Wilson didn't at least suggest the two chamber reamer dimensions for you even if they didn't want to share their whole die design.
For example, if they said go tight on the SAAMI specs, or offset some amount on those, or something along those lines, it would be trivial. I am assuming you are discussing a chamber reamer and not a die reamer?
There is only 0.001" offset between the ammo drawing and the SAAMI chamber drawing at the shoulder and 0.200"-line to begin with.
