Could some of the subtasks be small enough to be (or split into) Google-Code-in-2018 tasks provided by Design folks, maybe? Anyone?
I've detached this from T100270: Replace use of jQuery UI and MW UI with OOUI across all Wikimedia-deployed extensions and core; that's "only" for core and the ~200 extensions and skins in Wikimedia production; this task covers all 2000 such items.
