Just change her name to "Hope Sunflower Joy Peace Moon-Unit".
Her personality will follow suit, after a reasonable period of transition, and the problem will vanish! It's elegant, and that's always good. Time tested principle, too. I think...
The only other approach that could possibly work is much more expensive -- a series of long phone calls, originated at unpredictable intervals.
The name change is a much more economical solution, and much more reversable in the event of unpredicted complications, than genetic re-engineering.
If that fails, duct tape handles almost anything. There's always that! :>)
