Toolbar as Docker (or placing the toolbar in the docker area)

Hello!

I just got myself a graphic tablet (Wacom Cintiq). Yay!

So I am reworking the workspace.

I wonder if it is possible at all to have a toolbar be positioned as a docker? Or at the very least share the same space?

A picture say 1000 words so here's what I mean.

Thank you for reading.
