Dock Dual Thunderbolt 2 Laptops with dual HDMI out / dual screen sharing?

I have a 2013 Macbook Pro and a 2015 Macbook Air. The MBP has a busted screen but works fine otherwise, it has two Thunderbolt 2 ports. The Air is fully functional, it has one Thunderbolt 2 port. I like to make electronic music. I have some stuff on one Mac and some on the other. I have two displays I want to use. One is a older LG Flatron with HDMI input, the other is a 4K UHD smart TV. I also own a 2TB Time Capsule. In my head I'm thinking of a setup with the MBP is always docked, maybe closed if possible, always using the two displays, and a Bluetooth keyboard and trackpad controlling it or both. Then I could just add the Air to the docking station whenever I wanted to and share files and monitors. I was thinking I could use one for like VST and plugins and the other for my DAW host software. That way I could get the most computing power possible. I’m not sure if that's possible. For a minute I was looking into DANTE or AVB but then that wouldn't solve my dual display needs. I thought there has to be a dock that I can hook up both laptops to via Thunderbolt 2 and share data at high speed, with 2 HDMI outputs that I can also share between the computers. But so far I'm not finding anything. All I can find are dual monitor switches for mini DisplayPort or Thunderbolt 3 / USB 3.1 docks with dual display but no dual HDMI. (I don't need to power the screens with HDMI). So, I'm needing some help! I would like the added ports that a dock offers, I would like to quickly file share from laptop to laptop, and i would like to be able to, if possible, share dual external screens for editing and etc. Does anyone know how Ican accomplish this?
