I am making them, along with a friend who is an MS mechanical engineer that has spent his career designing and building high speed turbines. I have no concerns about the strength or material properties. People make long spindle versions of pedals all the time. It’s just that Shimano doesn’t. Speedplay, for example.
A longer spindle on the BB introduces chain line issues.
