"Any way to convert a RealTrack generated track to its DI counterpart without regenerating?"
YES
just rename the non DI folder Guitar,..._ORG
create a folder with the same original name then copy the contents of the DI folder to it
create a backup of the SGU
open the SGU
take the reverb off
save it as Artist Performance Track and drag out as a wav also.
now it's a wav, you can put the folders back to normal.
You are lucky you are using bb and you don't use real band smile
