I cannot see why it couldn't be done, but threading a barrel for conventional tubes seems like a better alternative to me. The shorter barrels certainly have their place, but with a cyl choke on most they are not very versatile.
One of my most useful barrels is one of the 21" Remington 870 turkey barrels that it threaded for tubes. It is short enough for SD roles with an open choke, with an extra full tube is a near perfect barrel for turkey. While far from an ideal choice for bird hunting it is certainly useable for small game, duck or quail using an IC or modified choke.
I know the same thing can be accomplished with a polychoke, but I don't see any advantages to the polychoke. I do see some pretty big disadvantages.
