You may be able to do some things with the shape of the steel to even reduce the thickness more. Such as formed ribs etc. if space allows

Thanks! Yes, hot rolled shapes are typically 36ksi, where as cold formed is 50ksi. I don't have room to deform the shape nor do I have time to engineer it but I could get cold formed in 18, 16, 14 and 12 gauge and essentially any leg dimension I need for it work.
