I wouldn't get too caught up on it just because they look different, treat it as inspiration and leave it at that unless you can modify it which you must if you have to use them. Quite often typefaces that are a bit on the extreme side like these work only in certain use cases, like very few if any.

Experienced type designers sometimes stay away from ideas like these not because they can't think of them but because in nearly every case you come to a point where a letter doesn't fit in with the style no matter what you do. In fact try for any of them, type out a few glyphs and you'll see some just don't match and the designer settled on something that is less fitting. Why? Because ideas like these stemmed from single uses cases like they got too caught up on a word or letter(common problem among letterers) and figured why not make it a typeface which always ends up with something unusable or as a last resort kept as experimental which will never see the light of day. Pushing the boundaries of type design is one thing but if it's completely unusable why bother?
