Welcome to the forums!
What you are trying to do is, indeed, impossible.
However, you can
make your taskbar auto-hide, so it becomes invisible when your mouse doesn't hover over it. This
tutorial explains how to do it.
And when it's hidden, you can use programs like Rainmeter
to create a "new" task bar where ever you like. This tutorial
will explain how Rainmeter works, and how you can apply it.
If you want your taskbar to become more "glassy", so you just can see through it, you might want to look at the Full Glass
and Full Glass V2
Both require Universal Theme Patcher, which you can get here
