If the team structure is the problem, you should disband the team and rearrange the structure so that it produces the result what you want. Trying to fit your product to the existing organization is not a good idea.

Conway's law: "organizations which design systems ... are constrained to produce designs which are copies of the communication structures of these organizations."

In theory, but you'd need Steve Jobs or Elon Musk level of clout to get that to happen. You'd need to be at the top of the organisation and pulling the puppet strings. Might be OK in a startup, but unlikely in a medium to large sized firm.

There will be people who need to make you fail or they are out of a job - they'll care more about keeping their job and paying their mortgage than you do about SPA architecture (unless you are at the top and have the vision as to why what you are doing matters.).
