Idk if kistler would succeed no matter how much money is thrown at them, either way they’ve gone bankrupt by Falcon 1 flight 4
Dream chaser just seems an intrinsically more complicated design even in its cargo form and wouldn’t get ready until the second half of the 2010s again not matter the funding they get, and it seems more complicated to use as a base for a crewed spacecraft.
Either way SpaceX already ate through $200 million of its CCdev funding by late 2008( vs $32 millions for Kistler at the time of its bankruptcy), funding which Is lost to any new competitor , and considering NASA’s funding issues at the time I’m not sure any second option could get serious funding going until ~2011
