You may be able to get things to work so that Tile Stories data (with the map itself) can be imported into one of the Hex Crawl modules that are out there. Two that might be worth checking out are:
Hexplorer
World Explorer
Tapping into the Foundry market might really help the reach of this app. Folks being able to use Hex Kit (now abandoned by dev?) tile packs I am sure adds to the potential reach of this app.
