The checkboxes have to be added in the form creation stage, so in either 
hook_form or hook_form_alter. Then in the hook_validate, set a variable 
on $form_state['storage'] and set $form_state['rebuild'] = TRUE; and 
check in your hook_form or hook_form_alter for your 
$form_state['storage'] setting, and if set then add your checkboxes.

I suggest looking at the form_example_wizard in the examples module, as 
that's basically what you are after, even though it's not a typical 
multi-step wizard you are after, the logic is still the same.
