Paul - Your coffee-soup can analogy is great, BUT the dimensions are a bit large. The bore variations from cylindrical are small, between about 14.5 mm to some 14.8, and may have several forms, also some makers use the "reversed-cone" bores. The most recent study [to my knowledge] is that by Lee Gibson, "Clarinet Acoustics" available from Amazon etc for some $15. To my mind the integration of bore-size and "character", tone-hole size and placement and pad "height" and other venting is greatly complicated, there are some patents [Carre in particular] which give info, but the real details seem to be "trade secrets". I like the subject but find it VERY complex! Don
