Hmm. There was a thread about the EMG E series as possible replacements for the Bartolini BH2s in Ibanez EHB 5-strings. They are the Bartolini P4 shape, 117x32mm, while the  EMG E6W is 119x32mm. These on the HILS look slightly smaller, 114x30mm? It might take a little woodwork or smaller pickups than those I mentioned.
