Like you I have a mixture of both serious intent and light relief comedy in my reasoning.
The more serious side is that putting T Szamboti, R Gage et al "on the stand" under oath and subject to cross-examination would destroy their nonsense claims and any remnants of credibility they may have. Sure they would keep on lying after the event but the claims would have been destroyed once and for all in an undeniably legitimate process and venue.
Hence my repeated advice to T Sz that he read the transcript of M Behe's testimony as a witness in
Kitzmiller v Dover The cross examination was not a pretty sight - and the shredding of the credibility of a creationist lying for his version of God should be a salutary lesson for any truther prepared to continue lying for his version of truth.
Meanwhile I like your "light hearted" suggested reasons:
My pragmatic perspective is that we will never see such a scenario - an investigation with Szamboti, Gage et al "on the stand". Even they must realise that it would not gain anything for them.
I wouldn't even put FF and his current contemporaries in the same ranking.
BUT - Debunkers - why not join with rwguinn and ozeco41 in a united call for a "New Investigation"?
