1688's battle that never was

Most people know the story; William of Orange lands at Torbay November 5th 1688 with about 14,000 men - mostly foreign professional soldiers. James II assembles his own army and marches out to meet them. James gets to Salisbury and suffers nose bleeds - Churchill and the Duke of Grafton desert with about 400 troopers to William's camp at Axminster. James dissolves his army and escapes to France. James had a numerically superior army and has been criticised for not having the martial skills to have made a fight of it. I wonder to what extent we can reconstruct this non-existent battle through army lists, orders of battle etc and see what might have happened? It might make an interesting display wargame.
