FWIW from my perspective it'll work better as a replacement rather than additional key combination. The reason for this is with their more recent laptops Lenovo in their infinite wisdom have placed the <PrintScreen> key (which in a traditional PS/2-keyboard manner produces <SysRq> when combined with <Alt>) in their keyboards between the right <Alt> and <Ctrl> keys. With thumbs not being as accurate as other fingers (and the overall misdesign of the keyboard and touchpad interface) you can imagine how often I have inadvertently hit <SysRq> combined with a letter key, wreaking havoc to my system (and of course I want to keep the key enabled for times when I do need it). Also Documentation/admin-guide/sysrq.rst mentions that you can set an alternative keycode sequence for KEY_SYSRQ with `setkeycodes <sequence> 99' already, but I find this pretty limiting as this only works for single keypresses rather than combinations of keys, because <sequence> actually refers to a single scancode (possibly 0xe0-prefixed).
