I don't know how to achieve the specific resize action you mention, but
I do know how to bind an arbitrary command to an arbitrary key combo.

In the manager, see the "Commands" module on the "General" tab. This
lets you bind an arbitrary command to an arbitrary key combo. You
define the command on one tab, e.g. command0, then bind it to a key
combo on the "Key bindings" tab. There is an example there (at least
there is in 15.10) that binds gnome-system-monitor-p to ctl-alt-del.

You can also bind commands to mouse button presses or hitting the edges
or corners of windows. This doesn't see to be how hot corners are
achieved in Unity though, as I have two hot corners but they are nt
visible in this module.

So if you can figure out a command to execute that will resize a
window, you should be able to bind it to a keystroke.

It's not exactly what you are looking for, but you can also define
rules for window management in the "Window Management" -> "Window
Rules" module. Provided you can identify a window by ID, title or
whatever, you can define rules about how it will be managed. i think
they are declarative though, not dynamic. You might be able to trick it
by (for example) having a command that changed the window title, plus a
rule for that title, but I'm really only guessing. And the rules may
apply only on window creation.

I have NOT used it myself, but the command wmctrl looks very
interesting in this context. Google "ubuntu command line resize window"
and look at a few of the links e.g. some of the answers in this thread:
