You're right - the form must be modal to use the TO clause, but there is an OOP way to do this. DEFINE an object that holds the variables you wish to pass back, then pass the object in using the WITH clause. Alter the properties in the object appropriately, then release the modal form. You don't even need the TO clause at that point, though I tend to use it as a logical to indicate whether the object was correctly updated.
