Looking good. I've heard people talking about moving a center overflow, but never seen it done.
What size are your drains/overflows?
I also think a Reeflo Hammerhead Gold would be too much for that tank; your drains probably wouldn't be able to keep up. The Reeflo Super Dart Gold would probably be a better fit. If you prefer a submersible pump, I recommend the Laguna Max Flo 4200.
The Reeflo Super Dart Gold does 3,010 GPH @ 6' head on 175 Watts
The Laguna Max Flo 4200 does 2,853 GPH @ 6' head on 160 watts
Both should be good options for your setup assuming your drains are 2". If your drains are only 1.5", you might be cutting it close and you may have to go with a smaller pump or just valve back a little.
What are you keeping in it? If it's in an unheated garage in Washington and you're keeping warm water fish, you may need some serious wattage.
