I like the idea of making sacrifice be something more significant. I've always felt running around sacrificing things to the gods when all I really wanted was to get rid of them.

I think you're You're right that having maintaining a list of what each god does and does not like sacrified would be too much work for too little benefit.

I do think that if sacrifice were upgraded there should exist a "trash" command that functions like sacrifice presently does (except perhaps without the small copper reward).

One idea I've though about occasionally is that sacrificing to a specific God might go on a prayer-like channel that echoes "bob just sacrified a berry pie to Pico" The immediately obvious problem is that this has the potential to create horrendous amounts of spam, if the players aren't clear on the difference between sacrificing (or trashing) and sacrificing to a specific God.
