I wonder (since 2007 at least) whether it might be feasible in the long term...
...to swap the 8*RB.162s for
- in the rear: tilting the TF306E exhaust downards, F-35 style (was ready in '72 through the Convair 200 and its F401 turbofan)
- in the front: replace them by two RB.189s, the third generation of RR lift jet after the Balzac RB.108s and this one RB.162s.
By this point the Mirage III-V would be no worse than a Convair 200, a Yak 36/38/41 or the Bae/MDD JSF entry (the one that lost to Boeing X-32 and Lockmart X-35).
