No, it is not possible. T is a parameter. You do not know anything about it. You do not even know if it can be instantiated at all. It might be a trait or an abstract class or a singleton type or a compound type.
That is the whole point of parametric polymorphism. To write code that does not need to know anything about the types it is dealing with.
Just as an example, it is perfectly legal to call your method like this:
val goodLuck = createObject[Nothing](Seq(1, 2))
Well, Nothing is literally defined as "the type which cannot have an instance". How are you going to instantiate this?
