Ideal style (pop off) Rada rollbacks are available, I have one in 9x12 format. They are also rare, most of the Rada rollbacks out there are for the more common slide in style (as found on Maximar etc).
ICA 726/3 backs will also fit. Generally 6x9 plate holders are cheap, you'll just need to scour ebay for them and be patient, unless some kind soul on apug has a few to spare. Film sheaths might be more difficult in 6x9, but you could use a bit of glass or perspex cut to size to hold the film in place. As you only have one plate holder at present, you could convert the film pack holder to hold a sheet film.
