If the above is correct, I'd still be somewhat concerned with this line by Sawakita (from thread I linked above):
"You'd have to repoint blocksets if you're going to extend them; it shouldn't be too complex if you're using the disassembly, it has already all the tilesets stuff disassembled and labeled. Maybe you don't even need to repoint them if the bank that contains the blockset is completely disassembled and has enough free space to handle the expanded data)."
Am I right about what I've typed above, or are there more things I should be aware of? Would love some reassurement or corrections.
