Thinking out loud here... What IF the length were optimized according to the Aerodynamic Template, and the end of the spoiler continued downward following the template?
To reduce the amount of lift under the decklid, extend the belly pan up at the 10° angle to meet the downward curvature.
At 45 mph, no need to worry about correct parchutes deployature. Wait, are we not trying to get rid of the natural parachute our cars create?
Could this be a boat tail without the kammback section, perhaps??

*The 'Template' doesn't produce lift,so in affect,the spoiler would be a solution for a problem we didn't have.
*The spoiler,extended,wouldn't really cut drag unless it was boxed in all around (box cavity).
*With a 10-degree diffuser up-slope,the flow would be detached and low pressure would migrate under the diffuser,which behind the rear axle,could induce a pitching moment which might lift the nose.
*Might be better to stick with 2.5-degrees,to 4-degrees,depending on where the diffuser originates,just to be safe.
