Belt Z axis: Rod driven by Wormgear

Hi Everyone.

I have been looking into a solution how to best drive my Z axis for quite a while now.
Ordered a Wormgear and a Wormrod. The plan is to attach the Wormrod to a Nema17 and the Wormgear to the 8mm rod driving my z axis.
The difference with my current setup, like in attachment, would be installing 1 long smooth rod and attaching the Wormgear on it, then vertically mounting a Nema 17 with the Wormgear against it. If the parts are well made i think i can eliminate backlash if i mount the motor as close as possible to the rod.

I made a stupid mistake and ordered the wrong bores, so i ordered the opposite bores for the parts (rod on rod instead of on stepper and Gear for stepper instead of the rod..) This is what i ordered [www.aliexpress.com]
I got some ideas how to counter this so i can atleast test the design.
