Wow, what a project!

Ok, it is (or at least it should be)
technically possible to do this in Simutrans.
BUT:
It might require
a lot of work, and it would probably be very tricky - both, to create
and to build in game.
It also depends on how strictly you want to stick to the original. Some deviations there might make a few things a little easier and more versatile as well... Let's face it: if you want to use something like your graphic (which is nice by the way) 1:1, you'd have to do what the japanese community did: use stations on the basic bridge, one for each tile. And basically this would require the bridge to be built in game with one specific length
only (as any single tile shorter or longer would distort the look).
However, if you decide to allow some of the cables' angles to be changed... then it might work with stations just for the area of the pillars, making things easier to build and allow for different lengths (within limits) in game as well...
As I said: a lot of work. And it might still come to the point where you find out it really doesn't work after all (or at least not well enough for you to be happy with the result).
