Can you build Lair's and Hive's (not upgrade like normal) without using Ice or IceCC?
In order to have them build normally you would have to use MemGraft. I don't think any iscripting is needed though.
I tried doing that but it only made the buttons disapear..
Are your requirements and Dats right? I believe there is a "Morph From Other UNit" Button in the Dats.
