Hello, Please get in contact with the creators of litespeed and create an easy way that cPanel support to switch between them. Litespeed have already done almost all the work for you. You could even do a deal with them for licenses and get cPanel customers discounts, but by default let it come with an option to change to their free version in Tweak Settings or something. Because of the software, it is so easy to switch between apache and litespeed that it really shouldn't be too much hassle. I'm recommending it to you, just to make things perfect, but already it's easy enough to switch over without the cPanel support (eg. doing it with their instructions works fine with their cPanel installation instructions). Thanks.
