The answer is yes.

It can, and probably should be called something other than, "Frank's version of YanoneKaffeesatz". The Step 3 you quoted, Mike, is clear on this point.

Why not call it "TalkGraphics YT" so both the work Frank and others did on the font is reflected, while retaining a sense of the creator?

Whatever is fine, certainly fine by me. We just can't release this as Frank's work, or mine, or anyone else's as "Yanone Kaffeesatz".

Call it "Your Own Coffee Sense Bold".
