Negative carriers for Saunders LPL 4x5 enlarger and Omega D series 4x5 enlarger

I heard that the negative carriers from LPL 4x5 enlarger can be used for Omega D series 4x5 enlarger. But will the LPL 4x5 accept negative carriers from Omega D series? Any lightleak possible?

I am also interested to know this, as I am trying to improve my carrier for a masking application. I am looking for one for the LPL 7452 (aka 4550XLG) that will accept 3mm as opposed to 2mm glass.
