SysRq when there is no SysRq key

My new laptop doesn't have a nice SysRq key. That led me to discover that nowadays, some keyboards come without SysRq key

Would it be a good idea, for those cases, to give the SysRq key function to the windows key?
And to do the same for keyboards where SysRq should be called upon by pressing Fn + F1 simultaneously, like on my new laptop (where it doesn't work, anyway, because the keymap thinks it's got a seperate PrintScreen/SysRq key)?
Edit: On second thought, the Alt and the windows key are located next to each other, when accidentally touched while pressing "o" the system would power-off. How much chance is there someone would accidentally touch those keys?
