I'm not sure 3 of these will replace what I have now.

Yeah it's hard to say, you might want to stick with the AI recommendations and go with 5 mounted the other way. The good thing you could always try 3 and see how it goes, if you find yourself running them close to 100% and still not giving the corals enough light you could always add the other two. IMO though if the 3 sols won't work then 3 Radions won't either.
