We can discuss this until we are blue and never agree and that is okay because the one you have to convince is the Building Official for you project. I can tell you the vast majority will not agree with you. However if your AHJ does then that settles it. I would not agree with your design and I would base my decision on the following
Effective Use of the International Residential Code
It is important to understand that the IRC contains coverage for what is conventional and common in residential construction practice. While the IRC will provide all of the needed coverage for most residential construction, it might not address construction practices and systems that are atypical or rarely encountered in the industry.
The building official is hereby authorized and directed to enforce the provisions of this code. The building official shall have the authority to render interpretations of this code and to adopt policies and procedures in order to clarify the application of its provisions. Such interpretations, policies and procedures shall be in compliance with the intent and purpose of this code. Such policies and procedures shall not have the effect of waiving requirements specifically provided for in this code.
