Why not?  If the converter implementations have a public zero-args
constructor, you could use a DI framework to create them, and configure
their properties appropriately.

The hard part for this use case is that the method parameters of the actual
conversion calls take a FacesContext and a UIComponent, so you'd have to
mock that sort of stuff up somehow if it's really a non-JSF use case.
