should be no problem.
cloudlinux has provided alt-php for litespeed before EasyApache 4.
with alt-php, no need "Build Matching LSPhp" when EasyApache 3. in other words, cloudlinux's alt-php is pre-built matching lsphp. so I believe cPanel and ClouldLinux will take care of litespeed themselves with EasyApache 4, just get rid of the needs of "Build Matching LSPhp" from litespeed. that's a good thing and we appreciate the effort of them.
