Sure it is!
Since the top-level form object ("form1" by default) is always a flowed subform, all pages have Instance Managers that you can use to add or remove instances of them.
By setting the page 2 and page 3 subforms as repeatable (check the
Repeat Subform for Each Data Item box on the Object palette's Binding tab) and having no initial instance (
Initial Count set to zero (0)), page 2 and page 3 won't exists at first. All you need after that is code on each radio button to either remove the instance of page 2, add an instance of page 3 and populate fields on page 3 with information on page 1 or vice-versa for the other radio button which adds an instance of page 2 to the form.
Here's an example of the kind of JavaScript you could use on a form which has a single "name" text field on all pages and populates this field on the page that's added to the form depending on which radio button the user picks (on a radio button's Click event):
// remove page 3 if it exists
if (form1._Page3Subform.count > 0)
form1._Page3Subform.setInstances(0);
// add page 2
form1._Page2Subform.addInstance(0);
// populate the name field on that page with the value of the name field on page 1 (this page)
form1.Page2Subform.P2Name.rawValue = P1Name.rawValue;
The attached form shows this code in action.
