Could Great Lakes yards build a Tillman battleship?

What if a wealthy industrialist enlarged the Great Lakes locks and canals in 1905 so a Tillman-sized battleship could pass?

Larger waterways would not settle treaty restrictions or provide the infrastructure and working practices for large warships; political support could still motivate the investment.

The scenario assumes that the locks and channels have already been enlarged enough for a Tillman-sized ship. Treaty restrictions on naval forces in the Great Lakes remain a separate issue, illustrated with museum ships and uncertainty about exceptions for modern construction. Building and servicing large warships would also require suitable infrastructure and established working practices. A yard's ability to fit a hull within its dimensions does not establish that it can build to naval standards. Political support from senators and representatives is offered as a possible reason to make an otherwise unattractive investment.
