You can. See Meditation.
At 20% SkS, a whopping 7k+ stat, you'd have reduced acceptable ping from its current maximum of 250 to... 200. 50 ms effect on a very small span of the playerbase, in order to allow for perfect sync for the 80+% of players at or beneath 200 ms ping.
Which means it can already only support 50 ms of ping. Why then have a weave space there at all? That defeats the purpose of the whole change. Get rid of it, allowing for perfect sync, and just don't wait until Trick Attack to hit Suiton. Our Ninjutsu will always outpace our Trick Attack regardless, due to casting Suiton on pull but waiting until a later GCD to actually use it. You do NOT need to use TA immediately after Ninjutsu.
By doing nearly nothing for either side. There are fixed GCD intervals, even given complete adherence to an optimal rotation, that currently allow for a perfectly timed Trick Attack. Scaling TA, rather than the things actually causing the desync, merely changes those intervals. Unless we are suddenly forced to stack SkS despite its low relative weight past entry gear, it's not going to add a single interval to that list, only change where they are.
