"Under-bridge" models for NWM

[Biriali]

Hello all 
I use these under-bridge-lots by kazuki (here's a link) all the time. They use an overhanging prop for the part of the road that goes under the bridge. And now for my request: would it be possible to make similar overhanging props that match some of the new networks from the NWM?
If some of you nice and resourcefull  people here could make such models, I would be happy to make the lots that would have to go with these under-bridge pieces. I have no idea how much work there would be involved in this process, so if I'm asking too much, please let me know.
cheers.
