Asking mate, TriStar K/KC can carry alot more fuel than Voyager. The 330 is virtually legacy anyway. The main issue is the cost of the whole thing. Their airships chose to "budget grab" as big a slice as possible and we see the result (no Harrier or Nimrod etc).
The plot was lost two decades ago. The airships chose not to seriously invest in TriStar as a long term platform and, they also chose not to fit the wing pods as a cost saving choice.
Yes, it is nice to have a new aeroplane for everyone to admire but, we get less capability than the platforms it replaces for £500Million a year for 27 years.
You say the TriStar was expensive, people don't realise how cheap it really was
