Something needs to “drive” the monitor. A driver card
It’s built into the 6kPro. But not the 4k.
So you’d still need some kind of processor to create the image for the display inside the EVF. That’s why it’s so small

Hmm, while I'd agree that it's unlikely that the display panel in the EVF takes HDMI directly, the interface to most display-panels these days is an HDMI-like serial stream of pixels plus clocks/syncs which may actually be encoded into those pixel streams. It doesn't need a frame-buffer elsewhere which is what I'm guessing you mean by 'driver card'.
I would however agree that you'd need something to convert the HDMI output from the P4K/6K to the flavour of serial-pixels that the EVF speaks, which could well be an off-the-shelf single chip solution, that would only need a few cm^2 of PCB - so I don't think size is necessarily an issue.
To be useful though, I doubt many folk would want to lose their HDMI output and USB-C for power, so you'd need an external power input and HDMI-pass-through. This adds connectors and complexty, which pushes the size and price of the adapter 'dongle' up. Would folk pay $150 for an adapter for a $500 EVF, or would they go for the Portkeys LEYE instead?
