Sure, you could do it that way, but... we've done this before... really.
Ah Video! You would think that working for a Media company, whose entire focus on content we would have a pretty clear game plan for our video platform. And you would be right! Sort of. Our US and International video platform was properly tested, both on the product side and performance side, and though it's not perfect it comes with plan, a data taxonomy and platform which to grow on. Strangely, i spend a lot a time abroad trying to convince to other's that this plan is at least a good starting point. I arrive, layout the project plan, wireframes, data/content plan and taxonomy. It all smiles, they say thank you, last hour or day they bring in a local designer who state's that there market is different - this of course is not based research, on testing, citing different KPI or even past experience, it's just that they know. I leave, warn them, they launch something it performs badly. I come back angrier, with the same info, wireframe, platform and strategy, and we begin again. I've gone through this evolution a number of times. I've slowly made head way, even if i can't be all places all the time.
The hardest concept is for managers to understand, that it's not just a technology and UI challenge, but a workflow, content and data challenge. Local Designers, make designs with limited sense of the scale, type and connected data between content. They may make something beautiful, but it can't be operationally supported, or it fails to let users see the connection between content.
