Well was curious, so took a look at the hak in question. One of the author's last posts indicated the next version was going to be fully CEP compatible. Alas, he never did get around to releasing it. The hak is listed as partially compatible with CEP, but that was 1.5x, NOT 2.x. It's been awhile since he posted last, but I suppose you could always try contacting him and see if he's got a copy of that version he might upload.
In order to get this to work with CEP 2.x, you'd have to go thru the 2da's and blend/renumber the stuff you wanted from the hak into vacant space in the CEP 2das. That would take some serious time, give the size of the hak.
There are a few clothing haks listed as CEP compatible on the vault...
