You are basically describing , a Kodak K16 processor which we used in 1973 for processing colour prints.
K16 - was a smooth smooth drum, it had a tray in front of the drum at waist height, which accepted the chemicals and when you lifted the chems fell
into the wash out tray.
Beside the drum system was a large tray with a large mesh and two metal snaps that would hold onto the drum system.
by presoaking the exposed paper, and preheating all the chemicals all you did was turn on the timer and the drum rotation.
lift up the hangers and mesh and put the print face down on the drum.. Yes face down.. pour in chem and time.. dump and pour in second chem and so on.
Calumet basket system- I used this as well
Calumet nitrogen basket system was a large mesh paper holder that had nitrogen burst on bottom( it had slots to put more than one print in at a time).. the tank holding the paper holder would have five ports where you insert the traveling paper holder into preheated chemical and water baths. the nitrogen burst would supply the agitation and you would move from tank to tank till you are finished.
With two or more paper holders you would be able to do continuous runs. Finish one run , take out prints to dryer, dry basket , load new basket - process.
These two systems were in my darkrooms at school and I used them for three years with wonderful results... the first hope RA4 roller transport
processor was installed the year after I left, I never felt I was cheated by using the K 16 and Calumet methods.
I liked using both methods, if I was setting up at home to do colour RA4 small I would use the K-16 method for sure , very compact and consistent.
up to 16 x20 print size.
For larger prints or more volumne I would use the Calumet Basket system.
But for large murals you are suggesting I would make my life easy and use some of the methods described above.
