From my understanding the new voices for the four 02 characters in Kizuna ended up very well received - especially Daisuke. Do you happen to know how the Tri voice cast was received in Japan?
From what I remember, it was about as good as you can expect. Voice actor changes done when the original voice actor is still accessible tend to be inherently controversial (even with the 02 quartet, they still were), and at the time, it wasn't formally revealed that Fujita Toshiko had actually been approached and declined due to poor health (it had to be kept a secret at the time on her request, which, according to Seki, put the tri. producers in a really awkward position). But most people were able to figure out what happened just by logical inference: some of the voice actors had retired, and the rest were swapped out for "consistency", especially since the Digimon voice actors were retained while the kids' were the only ones changed out. Some people did argue that "you could have at least gotten the ones that weren't retired!", but I think most people got it.
So, putting aside the people who were trying to stage a boycott over it or something:
I know Tamura Mutsumi's performance as Koushirou was particularly well-praised (this was before she ended up becoming super famous in the industry, since she's now really popular), and because of that quite a few Digimon fans were thrilled to hear her as Hiro in Ghost Game. It's probably the tri. performance I've consistently heard the most praise about, including even rave reviews from people who otherwise disliked the series itself.
There were people who said that Hanae Natsuki's timbre for Taichi was too distracting (on top of him not sounding much like Fujita at all, he was already a really famous voice actor by that point, so everyone recognized him as "Hanae Natsuki" too easily), but even those people all said that his actual acting ability as Taichi nailed his personality very well.
Hosoya's Yamato also got good reviews, which is interesting because he was also already a famous voice actor by this point, but I think it's because his timbre already enough in common with Kazama's that it didn't feel too weird.
Ones people were kind of iffy on were Mimi (although this also had a relationship with the way she was written in tri., I noticed people had fewer issues with her in Kizuna), Takeru, and Hikari (this one may be partially because both voice actors ended up breaking out into the industry shortly after in very different kinds of roles). Although this one I admit there might be some bias; I personally also think these were the ones that feel closest to miscasted to me, so maybe there was some confirmation bias from me noticing when others talked about it...
While we're here, in regards to the 02 quartet, Daisuke (especially Daisuke, dear goodness) and Miyako are generally well-received, but people tend to be more iffy on Ken and Iori. In the case of Ken, though, when you have the incredibly legendary Park Romi as his original voice actress, and when his new voice actor is Lounsbery Arthur who has his own distinctive voice, reputation, and fanbase, I think you were inevitably going to get some kind of complaint of uncanniness in some direction somewhere...
