Unmanaged switch into Powerline adapter

Hi all :)

I have a setup that looks like this currently:

VDSL Router (plus wifi) > Powerline > PC

I would like to add another PC via the Powerline, like this:

VDSL Router (plus wifi) > Powerline > Unmanaged switch > PCs

Will this work ok? I have done research that suggests it'll be fine, but wondered if anyone else had done this.

Cheers!
