Cabinets are mostly the same size, so I think they could make back the cost if it was not limited to OJ cabinets but included all cabinets.  PSA certainly thought so; I saw graded T3s at Hollywood Park.  I'd like to slab my T3(9) collection but don't particularly like the way PSA holders look.  GAI soft-holders them; worthless IMHO.  Forget the value issue for a moment; don't you think they would look sharp in the SGC holders?  
I think offering the service would be part and parcel of smart marketing, especially since many collectors will send in other cards with their cabinets order.  I'd probably even pay a premium for the service; after all, what would a nice frame cost me?
