Sure, it CAN be helped theoretically...like if TD wants to write it that way, he could without breaking the plausibility of the story.
The question is rather if that is the story he wants to tell. A story where everybody end up reasonable happy, with all three carnations being able to succeed or getting rid of their problem. And so far I don't think that is the path the story will go, even if the player makes optimal decisions.
'Reasonably' being the key word. Is the option to, say, help Veronica come to terms with losing her gym and getting her in the right headspace to start over a
reasonably happy ending if she doesn't win the contest? I think it could be, especially if it can be contrasted with a different ending where a beaten down Veronica becomes Samson's favorite house girl. It will depend both on what TD wants to happen and how he (and GIL, of course!) presents it.
Well, the more endings and variations the less fleshed out they'll likely be and/or the longer the development time will be.
The game already has the problem (and I'm not sure how it could be remedied in the way the updates are done at the moment), that depending on your choices some updates have very little content for you. So if you didn't follow the Veronica path, the last update had very little actual content for you. Now imagine the game have a lot of very different endings with very different scenes and you would have a situation in which you might not get any content from the last couple of update because "your" ending either was already implemented or is yet to come.
We'll simply have to see, what TD will come up with, but so far the game doesn't give me the vibe of a game that will have "perfect" ending if you just made the right choices.
Alternate endings are certainly labor intensive, but I don't think there's a worse place to skimp on dev time than the ending of a choice-based game. It's not only the final impression many players will have, it's the culmination of everything the game was building towards. You gotta stick the landing.
Mass Effect 3 did a lot of things wrong, but there's a reason it's the ending that became a meme.
