Buccaneer K.2 with bulged weapons bay and Douglas refueling pod carried internally until needed. If operating from a land base, install the SAAF booster rocket installation and use the S.51's larger underwing tanks. Ship-based version would use the standard underwing tanks. Both versions would have defensive countermeasures, electronic and otherwise, on the outboard pylons. Markings options could be British or other nations.
I don't know if structure and/or plumbing would allow underwing tanks on the outboard pylons, but this configuration with four such tanks would be impressive.
