What are you on about the terminal? The terminal has nothing to do with it. Not having stands directly connected to the terminal or airbridges is not a bar to operating.
The airport wouldnt be able to get it on the central apron but there is abolutely nothing stopping it going on the East apron where there are stands it would easially fit on and its not that far from the terminal (unlike DHL West Apron)
Though I hear there are plans afoot for multi-million pound redevelopments for the terminal anyway.
