I think that a LEO stopping someone for over weight is minor and that would not be my concern.

Do you really want to be in court defending any structural changes? Who designed the changes and who fabricated the changes and what are their certifications? And even so it will keep coming back and back and back as to how the manufactures specifications can be safely exceeded.
But we all make decisions and take risks...
If anyone should have ever been stopped it was me pulling a huge boat with a 65 Falcon and with no trailer brakes. That was an accident waiting to happen.
