Poorly cast look a likes will be an issue for the home grown characters too. Maybe I should reiterate; I don’t expect to see Luke or Lando walking around, but I would expect reference to them and to see R2 and C3PO, Chewie and maybe an Ewok or Jawa. Things easier to cast when someone calls in sick.I completely disagree that Disney will go this direction. They haven't made any attempts to hype up that this will be a main feature of the land and as Potter has proved, if you have a good enough product and a strong enough brand, you don't need to dilute it down by throwing poorly cast look-a-likes everywhere.
If they do end up going the character route, firstly they need to cast absolutely with perfection. Also, I could see a Poe meeting alongside BB-8. Especially if they're going to stick with the immobile BB-8... it's kind of awkward doing a M&G with BB-8 right now whereas Poe could add some life to that M&G.
