The group that built A1 Pacific 'Tornado' were a hard-headed bunch, with professional legal, business, and financial folk leading it (not just steam-heads!). They are about to commence a Gresley P2, and I expect it'll be running before too long.
But a Wellington? Why? And what would you do with it? As has been said, could you construct a business plan to justify the cost?
If it's to be done 'just for fun' with no business case for it to 'wash its face', then I'd think a Wellington would be well down most aviation enthusiast's list. It's not attractive, it didn't excel, it was wobbly and flexible. It was soon outclassed.
