Bottom line: Chiltern do not have sufficient stock or traincrew to provide additional capacity between London and the West Midlands during a WCML block and also provide additional capacity to Wembley Stadium.
Had they produced a train plan that tried to achieve both, it would only have needed a couple of cancellations for there to be significant safety concerns at Wembley.
It may be less convenient, but there are alternative routes available to and from Wembley. During a WCML block, Chiltern is the only direct rail route between Birmingham and London.
Given the DfT call the shots on timetabling and fleet usage now (single crush-loaded Voyagers on XC anyone?) I would also assume that Chiltern had to get the proposal approved by them as well.
