Maybe With Some Tweaking
Personally I don't think this design is very complicated, the mechanism to tilt the tub is unusual, but very simple consisting of a motor, rack and switch. The Whirlpool/Kenmore Combo of the 1960's and 1970's had a more complicated system overall than this by far. I bet it would have been lighter weight than some of the other Monsters that were produced. Comparing this to some of the other market combos, the interior of this machine looks rather roomy and might be relatively easy to service, although with that said, Frigidaire was never known for their ease of service.
The Agitator is definitely an up and down pulsator style utilizing a Unimatic direct drive style transmission. I have to guess that Frigidaire was serious about this design but decided to wait and see what kind of market share the combinations would command. They did something similar with their dishwasher, waiting until 1955 to introduce their first model. I can't imagine GM would take the time and expense to go through the patents process unless they were serious about the possibility of building something similar. They were not the only company to patent a tilting tub combo, others followed later with slightly different designs.
I believe there is a very basic flaw in this design in that the clothes would be stuck to the side of the wash tub and would have a hard time peeling off and starting to tumble. Many types of fabrics would just go round and round in the dry cycle, stuck to the side of the tub and never dry. Also with the agitator in the way, it would make less room for tumbling and might leave the clothes more wrinkled that out of a convention style horizontal access drum.
