Headlight switch options:, Who's added an extra relay? Options

[Prospectfarms]

Quik search reveals HL switch a common point of failure.

Long NLA, I saw a late-model NOS selling for $285, which is less than the last OEM price. Way too much for me, and I have an early switch anyway.

Since the switches are prone to break down, it doesn't feel satisfying to replace it with a used switch that's likely to fail soon anyway. (Sorta like the MPS problem.)

The late Lapuwali suggested several times that a VW switch (@$40 OEM, $20 aftermarket) could be converted of 914. His reasoning was they functioned the same: 1 Off, 2, Non-keyed power to parking lights, etc., 3. Keyed power to headlights. His theory was that the Porsche switch internally ganged terminals while VW combined the wires before entering the switch and therefore VW switches had fewer connections. He proposed an adapter plate that spliced the proper terminals that could then be connected to the VW Switch. I couldn't find a thread where that had been accomplished

The other school of thought is to relay the headlight part of a functioning light switch, prolonging its life. This suggestion confuses me because my reading of the diagram is that the "combination relay" already does this. For instance, current for the headlights seems to be supplied from 56 on the relay via closing 56 on the ignition switch. In other words, the HL switch does not carry the headlight current. So why another relay?

Am I mistaken? Anyone done either modification? How?
