I have build 2 simple prototypes to move the scroll-wheel:

I need an extra USB cable to test the second one, but i wanna save on money,
so i'm not sure when i'm going to be able to do tests.
i just wanted to share for those who have build separators and want a scroll.
If you build one and it works well, let me know and share some pictures.
It's not a priority for me to have this, because i currently don't really need it.

I opened up the mouse and removed a bit of plastic so the scroll 
cannot click when pushed down. This was easy to do with a sharp blade.
Then it's a matter of creating enough pressure on the scroll wheel.

This was what i ordered for prototype 1:

but i was not able to connect to belt like i saw in the videos below,
too difficult for me, the belt is too tiny. You need a leprechaun.
So i'm sure other people would have problems making this as well, unless you can find some pre-made belts. Hence i made prototype 2.

thought update:
For the second prototype, maybe using a thicker stick so you can attach a large wheel at the side where the hand is, so that it's a scroll wheel, operated slightly sideways. If a wheel turns out to be awkward, you could also try a more sphere like wheel.
You could also try "Female Thread Rod End Joint Bearings".
You could also try "Mounted Ball Bearings" instead of eye-screws, then you would need another way to adjust the height, like maybe placing some layers of paper or something under the mouse ?

I'm trying with a thicker wooden rod and tried to move it from the side; this works with the end of a balloon wrapped around the stick. Without it it's hard to turn to stick.
I'm not sure yet if this is better than just grabbing the end of a stick to rotate it. Need more tests.
