Not sure there's any faff for the sound guy , just at the cab positioning point , the sound guy is left with a single DI feed whatever the OP decides to do
Funny thing here is if we see the OPs amp as a pedal board , with a feed coming out into the onstage amp then there's no discussion , only as to how he outputs from the amp / board . It can be viewed as board because he's not using powered output effectively making the amp part of his amp redundant and just using it for preamp / effects
