I guess my point is that if you did find a compatible 6V clutch, you should be able to integrate commonly-available, modern pressure switch(es) to control cycling - even though such switches are used in 12V systems- no?
Kind of depends. Some could handle it but most of the compressors and clutches of that era were not designed for the continual on/off operation the temp control would require. When the engine is moving at a fairly high RPM it is a huge shock to start and stop the mass of the larger reciprocating piston affairs common at the time. A one time on and then maybe an off at the end of a trip or at least a few miles down the road wouldn't be too hard. An on and off every minute or two is another story.
If you do find a suitable compressor with a clutch, if it needs a go thru, finding compressor parts for some units of that era is another exercise in patience. The 12v Lehigh that Packard and several aftermarkets used is a perfect example. I can imagine less commonly used compressors are even worse.
