Oh shit, yeah. That could do it.

Edit: Or maybe a reverse pulley system to turn short pull on the bolt into long pull on the trigger?

It would be very, very difficult (but not impossible) to make this work.

The rifle is designed to prevent the hammer being fired until the bolt is more or less fully forward (meaning the the chamber is locked and safe to fire).

Fortunately it's the final phase of the bolt's travel forward that actuates the sear which authorizes the hammer to fire, but you can see from the video that there's only a few millimetres of travel at the very end where the sear is unlocked and the bolt carrier is still advancing at the same time. You'd have to rig your system to pull the trigger in those few millimetres of travel.

Doable, but not with a stretchy/sloppy piece of paracord. Maybe a finely calibrated chain or something else that doesn't have any stretch/slop.

Edit: Actually, it may not even be doable - not if the length of trigger pull and reset is longer than those few millimetres of final bolt travel where the sear is armed.
