To be under the limit, then go ahead and stack the gaskets and move on.

To be legal, you (or the customer) have to write a letter. It seems like a reasonable request is to have the wording changed to "Cylinder head gasket(s) may be replaced with any gasket(s) having at least the same total compressed thickness as stock."

Keeping in mind that someone may argue that milling the head down and then increasing the gasket thickness would be an advantage on some car(s) and therefore shouldn't be allowed. In which case it could be rejected. And then the answer to be legal is "new head". If this is the result then please do not come back here and whine about SCCA.
No more calls please, we have a winner.
