That is pretty much what I expect to happen. We know that Lisa (daughter, as you know) will be a very successful model. The initial way to reach that goal was through the contest; this door has been slammed shut. On top of that she's disillusioned with the industry, so we have to bring her back in somehow.
So she definitely will have to somehow get the feedback that she generated on social media and TV. Maybe Elena and / or Jenny saw it and can relay it, with the rest of the gang maybe being sceptical at first and after doing research decide they could do something with it. They remember that creepy guy offering a contract (and we know from the dev team that he will play a role in C4) and contact him. He will be his creepy self and scare Lisa and the gang off; I don't think they will sign with him since then we're in the ballpark of getting her out of it again. My estimation will be that he is with Tyra in C4 and they will play the usual pathetic villain role. (We already had Tyra realising during the orgy that she actually lost, she just doesn't know yet how much.)
In that situation we have an aspiring model (Lisa), a veteran model and mentor (Georgina), a fired experienced agency worker hell-bent on revenge (Cassandra) and somebody who knows the business side (MC) and can take the odd photo shoot. They could also bring in the one or other model that way, or Ryan for some guest appearances.
Not saying this will be the C4 plot, but this speculation is as good as any. Btw, tzhat's also why I think that (hopefully avoidable) pregnancy is endgame, what's the point of a successful modeling career for bikinis and lingerie when you constantly have to retouch stretch marks.
