If there was a driver, that required an expedient solution be found and there was a willingness from all parties to find such a solution, then a solution would be found...quickly.

And there was me basing it on 39 years experience in Technology, working on many major technology implementations, and running large Technology departments supporting multi-billion pound businesses...
The challenge is that no one has done anything like this on this scale and of this complexity before, using untested technologies - this is a recipe for budget and time over-runs.
Just creating the work-flows for all the different scenarios would take a year or two, then understanding the interfaces required between all the technology systems involved (some of which won’t exist yet), then you have to translate that into what is technologically possible, which will then be subject to scope change/creep by changes in the real world and political imperatives - this is what happened to the NHS IT Programme; people with no idea of how things actually work (on the ground doing the actual work or the implementors of technology) make sweeping statements like "well, it can’t be that difficult" without any basis in fact or knowledge.
Technology isn’t magic - you need high level requirements, which then become detailed requirements, which you have to find a solution for (both technology and business based - technology supports and delivers business requirements and solutions, it is not a solution on its own), and you then have to develop, integrate, test, re-work, re-test (repeat cycle until complete) and then implement (which is a major piece of work on its own).
As the Home Office slide so aptly put it
