4K Displayport 1.2 KVM to 4K Television?

[BecauseScience]

Now that real 60hz 4K DP 1.2 KVM's are a thing, I'm thinking about picking up a small 4K television to hold me over until the holy grail comes along. (The holy grail is 40" to 45" 4K non-IPS monitor with HDR FALD GSYNC/Freesync and > 100hz.)

The setup would be

• multiple PC's connected to 4K Displayport 1.2 KVM
• KVM to HDMI via active DP-to-HDMI 2.0 adapter
• HDMI 2.0 from adapter to 4K television
• TV would be Sony X800D, Sony X800E, Samsung MU6300 or similar

Anyone doing something like this? Should work in theory but anytime KVMs are involved...

Getting even crazier, what about using a HDMI source through the DP KVM?
SOURCE -> active HDMI to DP converter -> DP KVM -> active DP to HDMI converter -> TV

I have zero experience with DP or active converters. What are the odds this would work? Would HDCP be preserved?
