Modding the Landsmeet?

Here's something that always bothered me about the Landsmeet: If Alistair is made king, you can imprison Anora in Ft Drakon, but you must either make Loghain a Grey Warden or kill him right there, no debating, no calling for a recess, no other options. My canon Warden is a Cousland, and I know she would flat out refuse to kill a man in front of his daughter, no matter what he'd done! He is a war criminal, but he deserves a fair trial like anyone else (and no, I don't think the Landsmeet counts as a trial in this sense).

Could anyone make a mod so we can send Loghain off to the tower along with his daughter, instead of just chopping off his head?? It would make me the happiest girl in the world, and I'm sure other people would like it, too!

Thoughts? Is this even possible? Bueller??
