It surely needs to be comfortable to press with one hand.

Not my preference, but that seems to reflect the bindings I see "out 
there". So you could be a good person to gauge to alternative bindings 
theme.

Yeah, C-x seems easier, because at least built-in code uses ctl-x-map 
(which you can move wholesale) and 3rd party packages can be asked to.

But C-c doesn't have a dedicated keymap, so solving this seems like the 
first step. What could we do?

  (kbd (format "%s C-l" ctl-c-key-sequence) 'some-command)

?

Or maybe create a bogus ctrl-c keymap and then make sure to refer to its 
binding with something like

  (kbd "[C-c] C-l" 'some-command)

...I'm not sure, ideas welcome. Something backward-compatible would be 
ideal.
