Why not run a high pressure, in-tank, starvation protected pump in each tank, through a pollack 6-port valve and eliminate the surge tank/3rd pump?
There are various options for in-tank pumps which avoid fuel slosh starvation issues from Summit - inc Aeromotive, Holley and Summit's own branded one.
It seems simpler than running a surge tank and quieter than an external 044 pump.
