A full cooling system is gonna kick out the vent once it starts warming up, since the coolant/water mix expands. It has to go somewhere. That's why the reservoir bottle exists. You're gonna want to rig up something. Maybe go to a slick street rod style aluminum cannister that is a narrow upright style that fits into a smaller space. Check out Speedway's site and see what they have.
