I agree, if you're changing endian-ness then bitwise compatibility between in-memory formats are out the window by definition. Even if we're just declaring a packed struct containing a single int32_t it's not gonna match at the bit/byte level. Unless you define a single 'right' bit order and then swizzle/unswizzle every value being written to or read from a packed struct, but then that's becoming more of a serialize/unserialize which is a different thing.
