Any suggestions on a holder that could be used in a Whitman album?

What I would like to do is find a way to get rid of the slides in my bust half album without losing the protection. What would be great would be something thin like the kointain but the the kointain itself won't work because the bust half kointains use a standard kointain with an insert to reduce the diameter. The airtites on the other hand would probably be too much work because you would probably have to make all of the holes larger for them to fit. Does anyone have any ideas what could be used?
