Rear hub problems :(

I just received my hub adapter(Clam Shell)style,My problem "is" my hub is too small.

I have a 7 speed free wheel hub,I really dont want to use the factory unit and love the one i bought from Pirate "Great service btw".

Question is this?? Can I swap out for a bigger hub to accomodate the adapter and still keep my 7 speed setup??
is there a 7 speed free wheel rim that fits this unit?

I dont want to "rig it to work" keep it clean if you know what i mean??
I purchased the smallest diameter thinking it would fit
Thnx kevin.

Problem solved had my machinist make an adapter for my adapter,So these will work nice with a 7 speed hub

This is what he came up with.
I originally bought the adapter for the worksman hub size 1.58

I dismanteled it to get these pics for you.....Been a fun build so far
