Have you ever wanted to do this? I find the premise ridiculous.
But anyway, you're complaining that you have to work too hard to do unaligned loads (i.e. the wrong thing even if it should work on a particular machine) in C, when basically every other language makes you work more for basic systems programming tasks?
Whether unaligned loads can work on the machine level, it depends on the hardware. On some other architectures, you probably get anything from traps to unpredictable behaviour. It's totally fine that C does not define the behaviour for unaligned loads.
If you want to do some weird stuff like loading a single unaligned 16 byte quantity, where there was no "middle part" to begin with, just do memcpy then. The compiler might just do the appropriate thing on this architecture. Or if you need to closely control what's happened, write assembly then. But again, why would you even do this?
