Sirius would not be visible. You have three options:
1) Pick a different astronomical object. Venus (or should I say Earendil) would be worth checking out.
2) Do what Arthur C Clarke would do: go ahead with Sirius, but precede your story with a short note explaining that you know very well that Sirius should have set in real life, but it was thematically important that it be Sirius so you decided to move it 30 degrees in the sky.
3) Do what Tolkien would do: use Sirius, and create a mammoth myth cycle climaxing with a violent and terrible divine intervention in which the orientation of the celestial sphere is abruptly shifted in order to account for the inconsistency. Make no mention of this collossal epic in your story itself, apart from a subtle allusion in the philological roots of a minor character's nickname.
