Has anyone ported, or recreated, urob’s timeless homerow configuration for ZMK to Vial, or to vial-qmk?

I have a Piantor Pro, built by BeeKeeb; it is a QMK keyboard, and specifically uses vial-qmk. Vial, or flashing directly from the vial-qmk repo, is the only way I’ve ever successfully flashed or configured it.

I’ve never been able to use the homerow for anything other than layer switches because they’re the only things I can put a long enough delay on that I don’t get unintended modifier hits. urob’s Timeless Homerow mods for ZMK looks like just the thing, but given my failure to flash the board with anything other than vial-qmk (including vanilla qmk), I’m assuming ZMK is going to be a no-go.

Is anyone who’s a fast touch-typer using homerow keys for MACS with Vial, or vial-qmk, and if so, what’s your magic sauce for avoiding mis-keying?
