the impact of this would be significant. You should check out Issey Miyake's "A Piece of Cloth" (Issey Miyake: A-POC and 132 5) collection, which was clothing based on a single piece of fabric. It's old, like 1999 era, but the concept has come up a few times since.
https://www.moma.org/collection/works/100361 is a start, but there are other examples. Rei Kawakubo also did a collection called Square based on a similar concept. Yoji Yamamoto did a couple as well, there were a few moments in Japanese fashion that would work extremely well with a full garment knitter.
These pictures are the top level concepts, but the rest of the collections if you can still find them have more examples.
