In 1942 the Löwe project was abandoned in favor of the Maus, was the Löwe more of a plausible tank? If it was designed instead and built would more have been easily built and used compared to the Maus being much larger and being a nuisance due to its weight?
As an overall project, the Panzer VII was in general more feasible than the Maus. This was because it would have weighed about half as much, hence making it more mobile on both a tactical and operational level, as well as easier and less material intensive to construct, and the concept followed a clearly more conventional design philosophy, essentially being a superheavy version of the existing Tiger family of tanks.
However, it is obviously worth putting this into perspective - while the Lowe may have been more practical than the Maus as a potential superheavy design, this would not have made it viable by any means. It still would have been resource-intensive and fuel-thirsty, as well as further stretching Germany's already overly complex tank construction program to cover another new design. Moreover, it would still have tipped the scales at over 80 tons, making the Lowe grossly impractical to transport and generally inconvenient to deploy, especially considering the limited impact a scant few of these tanks would have had in such a large scale conflict.
