At a minimum a replaceable cartridge needs to have an additional supply of hydrogen - and that means a sealable connection (not something you would necessarily trust a muppet consumer with - a lot of people don't even know how to tighten a nut. Also if we are to believe recent speculation about RF excitation that that would need to be delivered to the inside of the cartridge somehow.
My speculation is that it is just the addition of an extra dose of powder through a sealable port into an oversized reaction chamber - the old powder may be somewhat inert but the new powder's activity isn't hampered by the presence of the old.
