My questions was if there is a way to make it work under those circumstances.

Sorry, but I have no idea how to make that light work with other chargers.

Another way... Easier?

I just replaced the converter on my '88 with a Boondocker. I have the power on light now working using a method which I think is true to the original design and was quite simple. The "Bill Worden" method has two subtleties. First it shows that the wall wart is AC - not DC. AC wall warts are a bit more rare these days but not hard to find online. The second is that the power on light is shown connecting to ground. As pointed out earlier in this thread, that is a deviation from the original wiring and has to be manually changed for the "Worden" method or others discussed in this thread.

I made the simple change of connecting one side of the wall wart output to the POSITIVE side of the converter rather than to ground.

Thus one side of the power on light is connected to "battery" positive and the other side is connected to the wall wart output - which is the same as the battery positive with no shore power (thus no light) and 12VAC from battery positive with shore power (thus light). Electrically this should be the same as the output from the Univolt and should work with any converter.

A picture of the wiring is attached.
