Warren Gatland has admitted he would relish a British and Irish Lions rematch with New Zealand at Twickenham in November.
The Lions held New Zealand 15-15 at Eden Park on Saturday to end the series one-all, with the tourists drawing just their second series in history.
Head coach Gatland's men rallied from their 30-15 first Test defeat to triumph 24-21 in Wellington in the second encounter, and edged to a gritty draw in Auckland to complete the trio of All Blacks clashes.
The Barbarians are slated to face the All Blacks at Twickenham on November 4 and Gatland admitted the Lions would fancy stepping in instead to take on New Zealand in an unofficial fourth Test.
Gatland said of the suggestion: "That would be good wouldn't it? You'll have to ask PRL (Premiership Rugby Limited) if they'd release any of the players."
England had already explored the possibility of pulling rank on the Barbarians to face New Zealand in that November 4 encounter but the Rugby Football Union (RFU) eventually had to give up that ghost.
The notion of the Lions stepping in for a rare home fixture would appear a long-shot at this stage.
But it would not be beyond the realms of possibility for the Barbarians to look to reassemble the 2017 Lions squad, just in their black and white colours and not the red of the famed tourists.
The 1973 Barbarians were effectively the 1971 Lions reunited in different colours, and that star-studded side dispatched the All Backs 23-11 in Cardiff in one of the classic all-time matches.
For any kind of repeat, or indeed for the Lions to take the fixture instead of the Barbarians, the English club governing body Premiership Rugby would have to agree to release their players to take part.
Lions boss Gatland walked into the post-match press conference at Eden Park sporting a fancy dress red clown's nose, in a pointed jibe at the New Zealand Herald.
New Zealand's national newspaper had mocked up Gatland as a caricature clown in the wake of the Lions' first Test defeat.
And New Zealand native Gatland was left unhappy with the media treatment in his homeland.
"The New Zealand public and fans have taken us to their hearts," said Gatland. "It's been a great series.
"What was disappointing for me was how much negativity was out there.
I think we should embrace this concept of the Lions, I think it's been brilliant. I think a lot of negativity turned the Kiwis off supporting the All Blacks.
