I amagine the standard databus may come in handy, as well as those extra hard points... but as a maritime recon aircraft.... never. Personally, I would imagine the MR4 will be an excellent standoff launch platform or aircraft supporting land ops (fast, good loiter in flight refuel etc), but I could never see any maritime role re-emerging.... You just have to look across NATO procurement to twig that one, with numerous NATO countries slashing any maritime support contingent.
