6 inch Indy is a dream line for me, I just rewatched the original three actually and it struck me how brilliant Hasbro could do it now (just look at Endor Han and Veers!).
Classic Indy (plus the half a dozen odd variants you could get, Tux and Rope Bridge battle especially), Marian, Sallah, Willie, Short Round, Elsa, Henry Jones Sr, Belloq in his suit, Mola Ram, Toht with an interchangeable hand.., Vogel, Walter Donavan.., for starters alone, it'd be incredible (and I'd argue just as desirable as some of the secondary characters for any of Hasbro's lines, especially if they went to town with the accessories).
I'd of thought it would've been a crazy idea but between Ghostbusters Plasma and the new Indy game, I'm trying not to get my hopes up.., Raiders is 40 this year too...
I know it gets a lot of grief but I loved the 3.5 inch line Hasbro did when Crystal Skull came out, counted down the days till I got that first wave. Just a shame some seemed so rare later into the series, and the character selection/costume choices were a bit "eclectic" at times
