To give more then 160 total slots they would need to remove something from memory first, unfortunately there simply isn't anything left to remove from active memory. That is why they mentioned the mog house, inside your MH there are many things that simply will never happen. You can't cast magic, use JA or WS's so all those animation index's are instantly free to be re-purposed into inventory slots. You won't be able to see that inventory outside your MH due to those animation index's needing to be present but inside the MH is easily doable.
There are very real system limitations to this game due to the developers desiring to keep all clients compatible with each other.
