There's this typeface. It's quite original, but not exactly one of a kind.
I like it very much.
But some things about it bother me. Some glyphs, the finish, etc.
I'm thinking of "remaking" it, by which I mean designing a typeface with a similar look and feel that would realize the same idea, but fix the problems I find in the original typeface. I won't use the original outlines, of course, and I might even refrain from looking at the original typeface while working on mine.
The result, as I imagine it, won't be as close to the original typeface as, say, many grotesques, or geometric sans, are close to each other. But since the original typeface has original characteristics and no very close relatives (as far as I'm aware), the resemblance will probably strike more. Also, the original typeface is around 10 years old and its designer is probably still alive and active, unlike Akzidenz Grotesk, for example...
What do you think, is such a project legitimate?
