Can you make existing customizable housing taller?

Like make an 18x18 up to 6 floors instead of the usual 4? I don't know where to edit the z to make an additional 3 floors. I have edited the gump art to accamodate the extra three floors, I have my house placement tool correctly showing the menu options. But if I place a 5 story it only lets me customize to the 4th. I would also like to know if you can make bigger plots? I am still learning how to do things. Any help would be great!

not that I'm aware of I think it's a client rendering issue that stops it where it is now and the custom house gump doesn't have the extra levels available and may be hard coded into the client.

Another alternative would be to remake the entire housing system.
