Sorry, Nessism, you're right! He'll get a trail increase by decreasing the head angle, and an addtional one by making the wheel bigger (both terms are in the equation). He can reduce trail by increasing fork rake.
The added trail should slow the steering but improve stability.
The hard part is to decide what the geometry needs to be without extensive trial and error.
