In Mahou Shoujo Lyrical Nanoha INNOCENT, the new manga that's come out, Precia is actually like this, mainly because Alicia is still alive in this version of the Nanoha story. She's a far better mom than the Precia of the original series, and can even be a bit embarrassing at times for Fate.
There is also a fanfic "Game Theory", where Precia is... somewhat better than in the original, all while in the classic MGLN continuity. Read it, it's awesome.
