this is MY petition for a brand new Indiana Jones action figure line!!! If you would like to sign this, please do. Maybe, someone somewhere important will see this and make this dream come true;...
You should set up an online petition at some place like http://www.petitiononline.com, then send it to someone who has the power to do something about it. Just post the link here and I'll sign it.
McFarlane can't make Indy toys (thank goodness) because Hasbro has the license.
I don't think a petition will sway Hasbro or Lucasfilm. But if Indy 4 actually starts filming, I'd be surprised if both Hasbro and Lucasfilm wouldn't want to merchandise the heck out of it.
