Accessing one instance of MainStage from 2 systems

I'm trying to figure out how to access MainStage from 2 Macs, both using Logic Pro X. MainStage is running on my key station setup (MacBook Pro LACO) in the back of the control room. I've attached a schematic of my set up as it is configured (below). I'm using the iConnectivity mio XL midi interface which has an integrated MIDI network connection. I've used an off-the-shelf Netgear switch to connect both Macs and have configured them both to see each other in their respective MIDI/Audio setup windows.

The ultimate goal here is to access my MainStage/Midi outboard gear setup from either system. Too, I'd like to be able to access my Keyscape patches from the key station laptop (Laco) as an external midi device with Logic Pro x that's installed on the main studio Mac. That would keep the heavy processing needed for Keyscape on the laptop so the recording Mac doesn't have to support both. That would require redundant installs which seems like overkill.

Wondering if anyone has a working knowledge of this kind of monkey business. I would appreciate any help. Thank you kindly in advance.
