Yep, I don't see any issue with that. 

Worth noting is that checks _may_ look the same as the MISRA/AUTOSAR rule but actually not check it exactly as it's formulated. Especially the latest MISRA C++:2023 guidelines have a very short rule headline, like "Avoid `reinterpret_cast", but then in the expansion there's many exceptions to the rule, which e.g. `cppcoreguidelines-pro-type-reinterpret-cast` does not implement.
