Note that Moloco does make these in plastic.

The running board supports on the rooftop would appear to be pretty easy to make, until you think about it... How would you attach them to the roof? I suppose that a squared off "C" would work with the bottom glued to the roof and the top to the running boards. Note that the bottom contour would be an issue, with alternatives needed for radial and peaked roofs and then let's not even get into the different proprietary roofs such as the PRR's two different roof profiles on the X31/32/33 series of cars. For a radial roof, you are SOL, but you could address this for peaked roofs by making the bottom into two tabs with bend lines on an angle to match the roof peak. Bending them would be pretty easy.

While we're talking brass parts, the Pullman side sill tabs, with their distinctive vertical parts would also be a neat idea. They are available in resin from National Scale car, but again, to be accurate, they shouldn't be thick. They should be "C" shaped with the cross bearers and cross ties fitted into the "C".

As “Latitudinal Running Board” is the official term used by The MCBA, ARA and AAR.

I suppose one could etch a simple L with the holes. Design it for one peaked roof, file it to match the radial roof if needed. Then use a short stub of styrene to support the center of the L, under the central board. That'd look ok from some angles, but not all. In the same fashion, a stub of PB wire into a hole in the roof could support the etched L, might look better. (Kinda like moloco did, except in metal.) Fiddly though. 



If you've ever built any of YMW's runningboard end supports, or the brake step platform, you know how complex, delicate yet strong they are once bent along their little fold lines. 
I was thinking something like this little sketch I just threw together on my phone. The blue is the bend lines. The YMW etched bend lines can go either way, so could represent many styles. The 'feet" would be easily tweaked with a needlenose to match any odd roof angle or irregularity encountered.

Using the plastic ones, I used thinned Barge cement to glue them to the roofwalk which can then be easily glued to a plastic roof
