You should try! Keep in mind Helvetica is very straight-up and constructed, even in the italic. There are no traits of fluid handwriting, whatsovever, hence some of those shapes in your sketch have no business showing themselves in a grotesque.

Hi gang! I only post infrequently, but I was puzzled about something lately and had to ask ... with all the riffs and homages to Helvetica over the years, hasn't anyone done a script version of the typeface? I assumed this would be simple to find, but after a bit of searching, I came up with nothing.
It seems to me that such a face could be not only beautiful (and in some ways, funny), but also fill what I perceive as a void of highly legible, non-expressive modern script faces.
I've attached a ridiculously rough sketch of what I'm talking about ... I'd love any leads to a face like this, and any opinions on whether such a face would be a terrible idea or not. Thanks!
