How would you do this?

No not service. Good point though.

Is the existing gear the disconnecting means for a remote building or structure? If so, the new disconnect would still have to be grouped with the existing per 225.34.

Because that is just overkill and was looking for other ways.

What is the proposed transformer inrush? Is there a generator on site? What are the odds the primary overcurrent protection trips on inrush if it is not even 125% of the primary FLA? What is on the secondary? If there are any branch circuit breakers, I doubt you will achieve good coordination with the primary which may or may not be a concern.

Does your facility meet the requirement of 240.90 allowing the engineer to size the tap conductors per T240.92(B)?

Sizing overcurrent protection for a 75 kva 208v delta primary at 200 amps or less is an Underkill in my opinion.
