Doppleganger Druid/Warshaper question.

[Malfunctioned]

According to the Warshaper Prc a character with the shapechanger subtype gains the flashmorph class feature and a character with wild shape would gain the multimorph class feature but if a character is a doppleganger (shapechanger subtype) and a Druid (wild shape) would they gain both class features or have to choose from one?

As long as you didn't use them both at the same time somehow I do not see a problem with having both. Of course I don't know the official rule on this.
