Can you remove metal siding on old homes and install T1-11 siding?

I have rehabbed several dozen old mobile homes and have always painted the dented metal siding to improve curb appeal. It’s lipstick at best and I’m wondering if these old frames can handle the weight of plywood sheet siding?

I have put 4x8 smart siding panels up (not the lap siding) after removing metal and the weight seems commensurate. Regular plywood is heavier and also requires a facing on it - so think using strictly that approach you might risk overloading the home.
