Can I remap SHIFT+CAPS LOCK in a virtual terminal?

I recently acquired an old netbook which has no backslash/pipe key. I have successfully remapped the caps lock to backslash using loadkeys. I would like to map SHIFT+CAPS LOCK to the pipe key in a similar way, in particular not using anything like xkb as I want all this to work on my VTs. Is it possible to do this using loadkeys or some other tool? Thanks.
