This looks ok, but I'm not sure it'll work form me. I need to tweak the Spanner a bit to centralize the line height vertically in relation to the left and right bounds

A simple thing to do would be to modify mrkp.  Something like this:

             (mrkp

                (lambda (x y)

                  #{

                    \markup

                    \override #`(line-width . ,(+ staff-space y))

                    \fill-line

                    \translate #'(0 . -0.5)

                    $x

                  #}))

You could of course calculate the \translate value, though this would be more involved.

 

and also use custom symbols for each bound.

It should be fairly straightforward to adapt the function to work with a list of markups rather than a string.
