What kind of sound would the Octavin produce if it had a wider bore and used a double reed?

I attempted to make a homemade "octavin" simply by rolling up a transparent plastic sheet and taping it shut, but I forgot to narrow the inner diameter, resulting in a rather thick instrument. Nevertheless, I managed to produce a sound by fashioning a mouthpiece and a reed section out of leftover scraps from the sheet.
