Unlikely. The change in the ‘chassis’ between gen 1 and gen 2 was fairly significant. The new Five is much closer to the PLAY:5 gen 2. 

Do you happen to know where I can get the measurements for both and compare?

Not offhand. I’d be looking at the web sites of folks who manufacture both types of stands, maybe Flexson? But you may need to do research in the web archives in order to find information about the older style stands, I’m not sure anyone still sells them. 

Thanks - But I meant the measurements for both  the PLAY5 V1 and the new FIVE. :)

Again, not offhand. Some Googling and the web archive function might help.
