28 gauge TC?

I may have posted this topic in the past but I recall someone online owning a 28 gauge barrel for a TC G2. I believe it was a custom offering.

What are your thoughts? Is this a doable project?

I like the concept of a lightweight shotgun for small game. Even though it would require a tax stamp, a short Handi Gun type of barrel would be fun for cruising the timber roads in Maine for ruffed grouse.

Just tossing that idea out there.
