Changing DataTemplates at Runtime

I'd like to be able to swap out data templates at runtime, but without the 

FindResource("fdds") as DataTemplate

Type of code I've seen a lot. I'd like to be able to just bind the template to look for the resource according to a property in my ViewModel. Conceptually I'd like to be able to do this, but the compiler obviously doesn't like it:

 ... ItemTemplate="{StaticResource {Binding Path=VMTemplate}}">

And then other commands would change the value of VMTemplate in the ViewModel. Is there a way to do something like this?

StaticResource extension is an immediate lookup when the XAML is parsed which means the Resource must be present at the start of the app. In order to set a template dynamically you will have to do something similar to the way your first line looks.

A possibility I have seen would be to make the DataTemplate have a custom control that extends ContentControl that has multiple DataTemplate properties that would then be able to select different templates based on a bound value from your View Model.
