Not very likely if you think about this one. The girl's father believes they've been lovers for months. If Soun had any idea Akane was sleeping with Ranma he'd have them in front of an altar faster than they could blink. He may be ineffectual in his attempts to make them say 'I love you,' but he can be quite persistent and this would be the one time nothing would stop him. After all, he would have the help of Genma, Nodoka and Kasumi to do this (the last two being the most important).
Honestly, if the girl was Akane it would have an easier time being with someone besides Ranma. However, that would be a fan fiction series in and of itself. With Ranma around, there is very little chance of that happening as Akane doesn't like any other guy enough to consider. There's Ryoga, but he's more of a big brother to Akane, and that wouldn't happen unless Akane has been acting throughout the series.
