The way to get more cable pull out of a given shifter is to increase the barrel diameter. That's not straightforward. If she hates the location as well, it's worth deciding if she wants a different shifter with a larger barrel diameter.
The way to get more derailleur motion out of a fixed quantity of cable pull from the shifter would be to try alternative cable routing. Try running the cable on the other side of the anchor bolt and see what that does for you. JTEK cable rate multipliers may be fruitful, but ideally you'd find somebody who would let you try a JTEK out for free and buy it only if you like the results. Otherwise that could get speedy.
