There are reports that Stardock's ObjectDock Plus ($19.95) can do what you ask.
This is the commercial version, not the free one.
I can't vouch for it personally, and unfortunately it seems impossible to try.
The Pro version doesn't seem to be available for download as shareware.
You might try to get in touch with their Sales department to ask this question.

The new Taskbar in Windows 8 finally spans multiple monitors, and can be customized so that the taskbar buttons on each monitor are the buttons for windows open on that monitor. You can also make both taskbars show all windows if you choose.
To access the new settings, head into Taskbar Properties by right-clicking on the Taskbar and choosing Properties. Once there, you’ll see the “Multiple displays” section at the bottom of the dialog, where you can quickly check the box to enable or disable showing the taskbar across displays.[howtogeek.com]

Yes. Windows 8 allows taskbars to be shown on all displays. To do this:
You can also choose where to display pinned and open applications. This allows you to show taskbar buttons only on the display where the window is open, on all taskbars, or on the main taskbar and the display where the window is open.
