Is it possible to use new Cubase 11 plugins - Squasher, Imager, etc - in Cubase 10.5?

I’ve purchased Cubase 11, but I’m still on Windows 7 Cubase 10.5, will it work if I copy the new plugins to the proper directory for Cubase 10.5?

You won’t break anything to give it a try. I’d guess (but not very strongly) that they won’t, but only one way to find out.
