Why not? You just have to scoot to Orzammar and Honnleath before going to Circle Tower. Anywho, this would be possible I think, since there is an apropriate boot animation - the one used in Redclife when you try to enter Dwyn's house. An option that seems appropriate to me is: "This! Is! Calenhad!" (Kick him off.) Alistair should bot be pleased, in fact you should lose approval, as it would A.) Mean the largely unneeded death of a Templar B.) Be similar to killing the wounded soldier in the Korkari Wilds, and C.) Just seems to stand against what he believes in and appreciates. Similarly, Morrigan, Sten and Shale should approve, while Wynne would also disapprove, as well as Lelianna. I think Zevran would approve, as would Oghren. Not sure, there. Either way, this would be hilarious, and probably the only option I ever used again, even though I am quite the fan of using an Intimidation check on the bum.
