Suppose you have
IModel model = new LoadableDetachableModel() { ...
you can get the model any time:
List<Item> myItems = (List<Item>) model.getObject(null).
First time you call getObject the model is attached (list is loaded).
Until it's detached, getObject(null) will always return the loaded list.

If I were just displaying the lists in a ListView that'd be fine,
however I'm not using it that way.
Suppose myDetachedModel is being displayed in a ListView and on each
iteration, I'm grabbing a value from the database (here's where I need
another detachable model) and doing calculations against it - for each
iteration in the ListView loop.
In other words, I just need access to the raw object data in it's real
data-type after I've loaded it into a detachable model - my question
is simply that, how do I get it back to its original type.

I'm not sure I understand you but you load the collections separately?
Can't you just do something like this?
class MyPage extends Page {
public MyPage() {
IModel m1 = new LoadableDetachableModel() {
Object load() {
return [load collection 1];
}
}
add(new ListView("l1", m1) {
...
});
IModel m2 = new LoadableDetachableModel() {
Object load() {
return [load collection 2];
}
}
add(new ListView("l2", m2) {
...
});
}
}
