Scripts nope, you'd need "scripted mods" to make it work. (dev on that was ditched years ago)

Modding, to a degree; however all it'll take is someone with a shitty computer to kill it. Crap computers are usually the reason when the turn ends for both players you end up sat waiting for it to happen. People tend to blame the servers, 90% of the time it's just because one of the machines is taking ages to finish sending it's turn info.
(server lag does happen, but not as often as people claim)

Due to the annoying turn lag issue etc etc I honestly think the best solution for now is what dash & dab did. Short tf + short timer. Finding the magic numbers where it feels right may take a bit of trial and error though.
