As much as I would be over the moon with GB/Eng winning Ashes/ 4-Nations/ World Cup etc. in League...I believe the reaction from the neutrals in the uK would be largely apathetic. For a number of reasons:-
1) The games are broadcast on SKY only and as such do not capture the neutral viewer's imagination....also the BBC knowing this give little air time to events exclusively broadcast by their competitor...ITV even less so.
2) The Print Media are largely in the RFU's pocket and so after a brief period of praise would then begin to deconstruct it:- Roo's not as strong as they were- sign of the wane of the game to RU in Southern Hemispere etc. They'd also start making up the usual "Code-Switcher" stories
