What do you mean when you say time aligned? Those graphs may indicate phase issues around the crossover region, so I would focus on getting the phase between speakers/subs optimized before judging better or worse at different crossover points.
Any changes to crossover settings and slopes will likely change the timing/phase response settings needed to properly sum the speakers.
I would also check the subs both separately and together to see if there's any phase issues between them, and I would measure at different heights to ensure the dips are not local SBIR cancellation between floor/ceiling.
