Diving into this more, "April is meant to be the pseudo-mother figure" is almost an understandable take going by '87 Turtles, but it doesn't hold up to scrutiny. Her role was to be an attractive woman that hung out with the monsters (beauty and the beasts), who could interact with other humans for them, allowing them to hang in the shadows. That's the core of the character, and making any rules as to what she should be like beyond that is silliness.
In the 80s show she could work a bit as a matronly character looking after them, going "oh you guys" and getting kidnapped a LOT. The show was campy and rarely high stakes, that was fine.
In the more serious Mirage comics though, after her initial story Eastman and Laird struggled more and more with what to do with her. Her life got flipped upside down by the boys and she just went along with it, not really adding much aside from occasional minor assistance or providing them with a place to stay. The comic would check up on her and she'd just be worrying for a couple panels.
2003 briefly tried to make her less of a damsel-in-distress, then forgot about her. She appeared less and less with time.
2012 for all its flaws made her a human that hung out with the boys initially because she needed them as much as they needed her, then stayed with them because they were her friends. Having them befriend another teenager, and having that teenager be April, is perfectly viable. She still could serve her core role "attractive woman that hangs out with them and does things they can't." Rise April failed from the get-go because the writers never gave a damn about having the boys hang in the shadows, they happily strolled up to people and interacted with them in broad daylight. That show's April was pointless. There's a reason we never saw them meet her for the first time, nobody working on the show cared about her enough to bother with that story.
And MM April is just shit because Seth Rogan rolls like that.
