I'm not quite sure where Evangeline can be only that she's probably frustrated there's not enough magic that she can age herself up. xD

Given the OP mention that a character will being any resources from their home stories that they may need for any reason into the real world, and that there's 2 Servants, Nanoha and a Date a Live Spirit, plus your character. I think that they world will actually have an overload of raw mana pumped into it. After all the base rules for at least the three first examples are almost the same (which was one of the main reasons I picked Tohka; she scales well against the Nanoha and the Nasuverses). I don't know of Negima verse is that compatible but at least mana for ask of them to spam attack there will be lots.

Actually, this overload of compatible magic being pumped in the world at once might as well be the source of some interesting problems for us all. A magic anomaly or two would certainly be fun.
