Good idea.
Or you could use a suitably fed regular 625 TV SAW filter, then convert and filter conventionally.
Many Amateur and Military SSB transmitters actually filter a DSBSC signal at IF using the Receive IF filter, which with a double balanced mixer is the normal output. I've experimented with DC (or a pull down resistor) to adjust amount of carrier inserted.
