Hori fighting stick3 question

Hey wassup guys,

Question about the Hori Fighting Stick3 for PS3. Would changing the 4 way restrictor to an 8 way restrictor like the Hori Ex2 for Xbox 360 be the same method? I.E. drilling holes that match the original areas? Just wanted to know before I decided to place an order for two 8 way restrictors at Lizard Licks.

Thanks guys.
