As is often the case, the black trim that runs across the width of the bottom of my windshield is cracked and broken with bits missing?

Can I just eliminate the trim completely?

In addition to keeping water out of the vents the trim acts as a plenum for the HVAC. It's supposed to have a "filter strip" across the front of it that intake air passes through. Depending on how bad it's already broken, it's probably doing a pretty poor job of both of those functions already but it is a somewhat critical piece of the (poor) design of the HVAC cowl.
