Then if they never plan to do a World Revamp, they could divide the old world into a few content blocks, updated it visually only and form Timewalking Blocks from it as well. So there could be a Lordaeron Block with Zul'Aman, Scholomance, Scarlet Monastery and Stratholme (the last three updated into some new form better suited for M+) with Naxxramas and events like Southshore vs Tarren Mill world pvp objectives and pve cauldron runs in WPL.
Heck you could have the Timewalking Season change twice during the expansion season for more variety and faster rotation.
