Nope. Cartridges can be made to work.

If you already have a solution on the hot-end, then I would suggest a "KISS method" update to the cartridge and it will be a lot more reliable.
Then you can print anything and you will be ready to use your new hub. See the Print3DForum for more information on printable hot-ends and cartridge rework options.

Again, I have nothing against reverse engineering this thing, but I need to know that what is out there is according to the original design intent.
