If I was pleased with the sound of the originals, I would not recommend winding them hotter.
The increase of volume is always altering the sound, unless it is compensated for elsewhere in the pup design.
I have advised many who came to me for hotter bridge pupĀ“s, surprisingly few have tried to balance them by height -
which is free and requires little skills- only time and ears.
Of course, there are situations that calls for a hottie too..
