Yeah... in my latest test game, playing as Eire, I let Wales go as a vassal and didn't stick up for them - it led to allowing me to play nice with Scotland and not wind up in any European wars at all. 
As far as the Brittany land-or-navy event, I think the event could stay with the slider moves toned down to 3 or perhaps even 2.... since we are talking about only one of the sliders, I think 3 is doable.
