Physical differences between the 3 different build tranches, Tranche 1 Typhoons are significantly different enough internally to Tranche 2/3 that upgrade further than the current Tranche 1 Block 5 (which does include air-to-ground capability, contrary to what some folk believe) is not viable. This is purely from memory so may well not be 'totally' accurate, but I understand that the internal avionics racks/bulkheads, amongst other things, are where the issue arises...
