I tend to watch a lot of Touhou (especially IaMP, SWR, and now UNL) and Tales series videos. Seeing some of these gave me a kooky idea.
Imagine if ZUN or Tasofro were to design a Touhou game that mimicked a game from the Tales franchise (i.e. Tales of Destiny). That would kick so much a**, IMO. Watching major characters of the Touhou cast like Reimu or Marisa landing huge team beatdowns and Mystic Artes on some big bad boss would be heavenly.
The very thought of Patchouli casting Indignation gives me goosebumps... Or of Youmu landing a Satsugeki Bukouken (Final Fury)... Or Mokou using Hien Messhoujin... that'd be amazing...
And then you'd have the skits. Skits in Tales have always been funny, so coupled with the humor found in Touhou, I don't think anyone would survive it without cracking a smile.
It'll probably never happen, but it's the thought that counts. Think this would be cool anyways?
