I think "Same Sizer" looks ugly because characters are stretched mechanically, so each line has different width. Ideally, the lines should all keep their widths, and the position should be stretched.
I think a better application of "all words have the same size" principle can be seen in Vietnamese calligraphy, which sometimes combines Latin characters with Chinese-adjacent writing style, e.g. https://commons.m.wikimedia.org/wiki/File:%C4%90%E1%BB%91i_-... (this is written in Latin script split into equal squares)
