Looks like the trailer could be worked with. New Ray has a 1/24th scale Peterbilt, lowboy combo that seems to be similar in design. Maybe a scale down version of this same mold even. I have seen modelers really make it look good.
BTW, this appears to be an exact 1/16th scale, while the Bruder and Tamiya trucks are 1/14th scale. Expect the side by side size comparisons to be difference
