There isn't a place to "register" new varieties.  You'll want to start by getting the varieties published in the numismatic periodicals or specialized club newsletters. and then included in standard references for the subject field if possible.  It would also help if they were recognized by subject experts.

If that generates enough interest in the varieties, the TPGs may decide that they will recognize them

It would also help if you have documentation from the country's mint indicating that they did make different varieties.  Makes it a lot easier.
