So, after that package has been loaded and compiled, you could reach into that package and change just the values of them keys:

# switch package
package HTML::Entities;
$entity2char{frac14} = '.25';
$entity2char{frac12} = '.5';
$entity2char{frac34} = '.75';

# switch back to your package
package main;
# go on with your code
