If I understand correctly you have separate MIDI tracks that send it's MIDI to the drum VST. It can't "send" an EQ along with it. It's only note data and only becomes audio once it passes through DrumCore.
I would set it up like this. DrumCore on the grey track. Top blue folder is just there so you can collapse all the MIDI tracks into one folder to get it out of the way.
Now you can set separate effects on each drum on the yellow tracks but also common effects on all of them on the drum bus.
