In base game, they say this:
"Irritated Declaration: There you are. It has been extremely difficult to track you down, Jedi."
"Quick Clarification: But now that we have found you, we hope that we can facilitate communications."
"Unnecessary Addendum: And put an end... to hostilities."
In TSLRCM, they say this:
"Releived Statement: Oh, Jedi, it's good to see you intact. We were concerned that shooting down your shuttle would damage you irreparably."
"Quick Clarification: But now that we have found you, we hope we can facilitate communications."
"Unnecessary Addendum: And put an end... to hostilities."
In K2RC+, they say this:
"Irritated Declaration: There you are. It has been extremely difficult to track you down, Jedi."
"Releived Statement: Oh, Jedi, it's good to see you intact. We were concerned that shooting down your shuttle would damage you irreparably."
"Announcement: You have caused us to expenditure a great deal of effort to find you, Jedi.
"Quick Clarification: But now that we have found you, we hope we can facilitate communications."
"Unnecessary Addendum: And put an end... to hostilities."
"Threat: Come with us without resistance, Jedi... or you will come with us in pain."
The way I see this, that both base game and TSLRCM go for a somewhat-different-but-consistent tone. Base game HK squad is irritated-annoyed, TSLRCM HK squad is snarky assholes. And I don't think mixing the two styles flows all that well, because even if it's different droids saying the different lines, it's nigh-impossible to tell them apart because they all look and sound the same, and they are against the same backdrop too.
In more detail:
I think the first two lines of "Irritated Declaration" and "Releived Statement" are an either or, because they are tonally so very different and both sound like a definite beginning to a dialogue.
"Irritated Declaration" and "Announcement" kinda say the same thing but worded differently, it feels like too much repetition in this dialogue
I think them closing off their opening lines with the "Unnecessary Addendum" just fits oh-so-much better with the snarky-snobbish asshole personality that most HK-50s have, not to mention it's their catchphrase too. Having the "Threat" in there is again, feels out of tone for both base game and TSLRCM personalities, and kinda curbs the effect of their catchphrases too.
