Obtaining a customized variation of a class identified by a decorator

I am working with a class that is defined as follows:

class Person {
    @OneToOne()
    pet: Animal;
}

Is there a method to obtain a transformed type that appears like this? (Including {propertyKey}Id: string to properties through the use of a decorator)

// Utilizing generics
type ModifiedPerson = SomeGeneric<Person>

// Possibly using functions?
type ModifiedPerson = typeof someFunc(Person);

// This is what it would look like:
type ModifiedPerson = {
    pet: Animal,
    petId: string,
}

Asking for this capability in typescript at the current time is not feasible. There has been a longstanding issue raised on GitHub since 2015, which can be found here.

The use of @Decorators does not impact type.
