2" shanks in 3" circular tower

Do any of you have 2" shanks with elbow tailpieces set up in a 3" circular tower/pipe ? Plans are in the works for my bar. I am aware of the elbow shanks/tower shanks. I just want to see if the 2" might work.

Thanks!

The gooseneck tower shanks are available from Kegworks.com.

I have standard SS elbow tower shanks in mine.
Don’t think the 2" shank w/ the elbow tailpiece would fit, the elbow is approx. 7/8". And the elbows are typically welded to the shank.
