I definitely think MtD would do exceedingly well using Chronomancer. The biggest loss I see here is that of shattered concentration. That being said, using Chrono instead of domination/inspiration/chaos will give the highest dps possible for a condi shatter build. Why? Simple:
Illusionary Reversion & Chronophantasm synergizes extremely well with Sharper Images & Confusing Combatants.
These skills are so “revolutionary” because it helps us to shatter without losing out on 50%+ of our overall dps. The ability to give a full shatter AND keep clones busting out bleeds/confusion is not to be underestimated.
Now, going into Chrono for this dps boost obviously means you take a concession somewhere else. Whether that be team/self sustain (Inspiration), self-defense (Chaos) or boon rip (Domination). It’s hard to say which is best. In fact, I think arguing over which is a pretty fruitless task, but it is my opinion that even with Domination being the “dps” line, you will get more mileage out of Chrono in this regard based simply on those two traits.
I’ll definitely be trying out Chrono/Illusions/Dueling, but I think giving up shattered concentration might be a hard pill to swallow for me. 
As far as chronophantasma goes, I think it really depends on what weapons you use. That will determine the mileage you get out of it. If you use scepter/pistol staff, I’d see chronophantasma to be really helpful. If you use torch or shield, I don’t think it will be worth it simply because the amount of conditions those phantasms can dish out aren’t really great enough to justify chronophantasma over seize the moment (never underestimate how much quickness will help you) or lost time (slow looks like it could be strong, plus its just another condition for the enemy to be pressured by). Illusionary Reversion could in fact be strong enough to replace DE, but I’m still worried about it not being enough, and DE+iReversion would be too much, but without DE it could be too little. The other main problem I can see with illusions/dueling/chrono is a lack of condition removal outside of traited torch (which you’d actually have room to take) or the cleanse mantra (if you don’t take portal or decoy or a well). Its just that shield might be nicer than torch for some builds if you do take interruption traits for dom or chaos.
As far as the other traitlines go, while dominations boon ripping is so great, theres really little else of use in that tree aside from power block’s occasional usefulness. Chaos is similar, in that chaotic dampening looks promising for more sustain and the grand master traits could be pretty nice as well. Inspirations though looks also pretty interesting just for the condition removal and the healing shatters. I’m interested in seeing how a more self-sustaining inspiration/illusions/chrono or inspirations/illusions/chaos set up would work, maybe with a settlers amulet. I don’t think it would work really well for conquest since mesmer can’t really tank a point even with the extra sustain since movement and avoidance and kiting are so important, and it’d just take damage away.
Its obvious that MtD builds will be better across the board with illusionary persona and the utility of chronomancy, but I’m still not convinced that they’ll truly be viable compared to power shatter (that will probably also use chrono). This is because as it stands, power shatter just kills things faster than condition, and is better in team fights. Condition on the other hand has marginally better sustain and less thief weakness. Its just that extra sustain 1) isn’t that much better with rabid 2) is worthless when mesmers don’t have the tools to tank a point like any of the celestial classes.
Mesmer may be able to apply torment and confusion against one or two targets to an extreme amount, but they are still pretty outclassed by other condition classes. It honestly feels most similar to a necromancer thats reliant on AI surviving long enough to apply conditions (which is why necro is a quite a bit better). Mesmer doesn’t appear to have the heal and boon spam necessary to fulfill a celestial role either, and I don’t think the buffs will change this fact enough. Its still a fun build though.
Wow I got really ranty, but I hope I made my point hahaha.
