I'd look around on edakrill, maybe someone has already drawn these.

I used to design breadboard wirings using pcb-rnd; the trick was to use
many different layers so crossing wires don't make galvanic connection.
It's possible, but takes manual effort, not very convenient.
A code upgrade scenario that would let you do what you want:
1. upgrade find.c so that line-line intersections are not checked for
connections, but still keep line-via and line-pin intersections as conn
2. when you draw your routing, always use a via where you want to connect
two wires
3. always use pins on terminals where you want wires to connect
Assing a config setting for this sounds like a 30 minutes task, and it
would aloss help breaboard use.
If you are willing to test it in svn version of pcb-rnd, I am willing to
do it.
