HF impeller outlet to filter ring transition

[kayak]

On the HF dust collector, the outlet of the impeller housing is about 6x4 inches, then gets choked down to a 5 inch round house. Not a huge choke, but a choke none the less. On an Australian woodwork forum I read about someone that replaced the round hose with a rigid adapter that matched the dimensions of the outlet on the impeller housing.

Has anyone on here tried that, and if so, HOW, and what did you think of the end results?
