I agree, chances are the conversion is not worthwhile. But you never know 'til you ask. For example, think if the a/c system could easily be converted to manual control, like a simple swap with a 240D. I bet about half of us, the half with persistant vacuum leaks, would have done it.

Would not exactly call it easy. If you had a 240D and your "modern" car sitting next to each other, think about the job.

Remove both center consoles. Which means removing both drivers seats.
Remove both dashes
Recover the freon from both AC systems
Remove all controls, keeping track of all controls and their conections
Remove both evaporator boxes.
Replace the evaporator in the 240D box that is going into the "modern" car ( all that work and not replacing the evap would be foolish)
Installing the 240D evap box into the "modern" car
Install the 240D dash into the "modern" car ( center air vents and air temp sensor design difference, hopefully the same color)
Install the center console. Either the 240D console or put the 240D switch panels in the "modern" cars center console. AC switches are different
Figure out the wiring.
Replace the mono valve and tubing with the 240D heat control valve in the engine compartment.
Remove the water circulation pump to the ACC system.
Connect everything and make sure it works.
Charge the AC system and hope you don't have any leaks.
And after all of that the 240D still uses a vacuum element for recirculated air.

It is possible but after removing a 300TD AND a 240D evaporator box to replace the leaking evaporators, I find it easier to just keep the systems going as designed.
If you wonder what it looks like.

So the topic should change to "How can we help you with your vacuum leak problems???"

I would rather work on a vacuum problem than swaping a AC system.
