To be more clear, I do not think the cloned units should show up in the homeworld screen. That implies the spacer guild is involved with delivering them, which is wrong. My only point was that the AI which decides to buy units off the homeworld screen can also decide whether to buy cloned units. We need to decide how and when the selection of cloned units happens, since it will be somewhere else. In FFH, world spells appear as an action button on any unit; spells which can only be cast on a city show up as an action button on any unit in that city. So perhaps the ghola action shows up as an action button on any unit, in a city with an axlotl tank? Clicking that button gives you some popup, where you can select the unit to work on.
