Masking wp-content/includes using .htaccess

Hi,

How does one go about masking wp-content/wp-include in wordpress? i.e.

http://127.0.0.1/site/wp-content/ -> http://127.0.0.1/site/assets/ and http://127.0.0.1/site/wp-includes/ -> http://127.0.0.1/site/libs/

using .htaccess as some plugins/themes have wp-content hard-coded?

Thanks
