Fire in the Blood Trombone Choir (I would love input!)

I have arranged Fire in the Blood by Paul Lovatt-Cooper for 16 trombones and timpani. My first thought was to simplify it further for trombones; instead, I mostly left it as brass bands play it (see    • Black Dyke Band: Fire in the Blood - Paul ...  ). Condensed score available    • Fire in the Blood Trombone Choir Condensed...   Is this arrangement playable for a top college trombone choir? Could the trills be done, perhaps with the F-attachment? Please leave any help in the comments.
