Reducing inlet restriction...is this idea overkill?

Currently my Danner Mag 3 just uses a 1/2"...darn, what are they called...well, a little plastic thing with 1/2" NPT male threads on both sides. Ah, a coupling, that's it. :) Anyway, it has one of those on the intake, and my clearflex stretches around it to provide as little flow restriction as possible. I was wondering...would it be overkill (if there is such a thing :D) to use a barb adapter and a piece of 3/4" tubing to stretch over the outside of the inlet? Kinda like a little mini-res...that would give it as much intake area as it has when it's run submerged.

people have been doing this with 5/8" inch tubing, but you might have a hard time stretching it over 3/4".

With 5/8" you have a 1/2" ID so youde have a 'true' 1/2" setup. The thing is, the barbs on the Block and Radiator will have to be upsized to complete this 'true 1/2"' circut.

No, that's not the idea...currently I have a 5/8 barb so that it's 1/2" ID already. My idea is to stretch 3/4" ID tubing over the outside of the female threaded inlet, so that I'll have 3/4"ID or so at the very last section right into the intake. Basically no barbs on the intake at all.

I say go for it, I have tested stuff along those lines with my maxi-jet 1200 and it does seem to help. It seems to help the intake be more smooth and seems to help performance a bit. Also it probably will help extend the life of the pump since the pump is taking in water more evenly~less vibration,stresses on the impeller etc. Restricting the intake is one of the worst things you can do for these watercooling mag driven pumps.
