Perhaps, dare I say it, by 2004, Hank just couldn't be bothered about switching pickups when playing live...he had his generic 'modern' Hank sound and that was that.
The compromise was perhaps the different echo settings for different tunes, which settings were probably controlled and changed off stage by his guitar tech...plus the fact that they played a lot of old loved material which had never been played live ever or for years, to please their old faithful fans...
