You have two further options,

1.Try the same with another USB stick. I got the issue resolved by this way.

2.Wait the El Capitan final release.

Tom I had that problem with a USB larger than 11 GB. Partition your USB so that your installation partition is < 11 GB.

Weird, but worked for me.
 
Well, tried another USB pendrive and I finished Clover installer creation, thank you Tom. Now the machine boots fine from USB but it hangs at about 3/4 of the bootloader, then a KP happens saying "no HPETs available cpu configured incorrectly". Tried on 2 different machines, both hang with same KP at the same point. Still testing but I guess we'd better wait for a MultiBeast installer.........

Or load NullCPUPowerManagement.kext like would be used with Unibeast.
 
Thank you for the hint RehabMan, I'm gonna give it a try.....
 
Tried your fix, no luck same KP.
Could you please take a look to my DSDT? It works fine with Mavericks 10.9.5
