Thats a good thing to do. All the turbine heat at startup and cooldown goes up, and having a top hatch helps to keep the temps down in the fuselage during those operations, not to mention that in case of a hot start you will have a chance to put down the fire.

Keep in mind that the F15 has a quite high internal air pressure in the fuselage while in flight, and a large and flat hatch tends to bend and even get thrown out the plane due to this pressure. You will need to attach it in four points and build a inner structure to avoid this bend and torsion.. some internal spruce strips and some carbon fiber glued with epoxi will do.
