[TowerTalk] Mounting 1.25 stinger in 3" tubing?

I'm rebuilding my 40m 4-sq verts and have some 15' lengths of 3" OD/ 
2.75 ID tubing to use on the base end.  And for the "stinger" end, I 
have some tapered elements off an old yagi that are 1.25" OD on the 
bottom of the 17' length.

Other than buying some concentric lengths of aluminum to step from the 
1.25 OD stinger up to the 2.75 ID base tubing, any good ideas of an 
interposer that would take up some of the space?
