Silly question but has anyone any experience of stacking radiators?

I had an idea for a custom case but I was thinking rather than have say a 360mm radiator have 3 120/140mm ones face to face (maybe with a fan between each, ie rad / fan / rad / fan / rad)

but then to also angle the radiators to something like 45 degrees / | / | / thus reducing the height required to say 80mm and shrouding it all so I realise the width would be the same but the height is the issue and I would have to use smaller fans and also it wouldn’t be as effective as a single 360mm…

I know sounds a bit of a strange idea…
 
Linus did a video on this awhile back and yes it does bring temps down but its diminishing returns and rather pointless.
 
Two stacked 30mm rads isn't going to be massively different than one 60mm but I suspect the single 60mm actually has more fin area.
