Here's the most obvious question in the world on this topic.  Are capes

"capes" as in Beaglebone capes might not be due to the mechanical 
constraints you listed.

"capes" as a concept of pluggable hardware might well be. here is a real 
world example of commercially available pluggable hardware add-ons on a 
Linux system back from 2008:

depending on the add-on, different interfaces like GPIO, UART, USB, SPI 
using the same pins were used and there was no reboot needed to load a 
new hardware configuration or change the pinmux
