Would have loved a Season 6 with Future Jade.
The episode before the series finale, J2-Revisited really seemed like they were setting up a story-line for the sixth season... Had the show continued, I would have loved to see more of Jade interacting with her older self... Heck, I think there's room to get Stacie Chan back and create a spin off with Jade and all the classic characters returning... The J Team, Uncle, the Enforcers, Hak Foo, Valmont, Shendu and Drago... And of course Jackie.
Seems like she has a career in broadcasting, but there's still room for voice acting.
