I totally figured out a way to do this using rules and forgetting the list control idea. First I stacked my 5 textboxes vertically like a list in the section they needed to appear then:
1) In the checkbox control set rule; If checkbox1 = true, set field1 = value1
2) In the textbox controld set condition; if field1 is blank, hide textbox
This allows my makeshift list to not have any gaps in the event a checkbox is not checked (=false).
So simple (which is all I needed for my purposes).
