keysym BackSpace = Delete
keysym Delete = BackSpace
remove Lock = Caps_Lock
keycode 0x42 = Control_L
add Control = Control_L
$ sudo apt install gnome-tweak-tool
then use it to map caps lock to ctrl, and swap left-ctrl and right ctrl to hyper
would rather have meta in center left and 2nd from right
would rather super and hyper work
