GoAccess installation

I see that Webalizer will be deprecated in v140 and GoAccess will replace it.  It also appears Webalizer will be removed in v142.   Our server hosts many customer websites and we use custom scripts to pull data from Webalizer to provide to our customers (they don't have access to cPanel).  We will need to migrate our scripts to use GoAccess instead, but we will need time to do this before Webalizer is removed.   I am concerned that the time between v140 and v142 is unknown and may not be sufficient for us to modify our scripts to use GoAccess.   Is it possible to install GoAccess prior to v140 so we can get a head start on our migration?   Would early installation compromise or otherwise affect the cPanel-directed installation when v140 is released?
Thanks!
