As an alternate solution, you could lower the organic build rate of space yard components, but not remove it completely, and raise the organic cost of the colony component.

The limiting factor of fighter construction, and ship construction for that matter is typically the mineral content of the designs. You could probably find a ratio that make the colony ship inefficent enough to build on location, without seriously affecting the fighter build rate of the space yard comps, and without greatly increasing the build time of the colony ship on the homeworld, without requiring any further modifications. If it makes the maintenance too high on the colony ship you could add a slight maint reduction for the colony comp as well.

No it wouldn't totally remove the possibility of someone building a colony ship onsite. But the reason they are doing it is because it's quicker that way. Take away the incentive, and if they still do it, so what?

No, it will totally cripple AI - AI will still try to build colony ships on base space yards.

One of the major features of Proportions is that majority of ship building occur on orbital space yard - it takes too long to get a productive planetary space yard even on your first colony and you can not keep up with just one homeworld spaceyards. Any changes to space yards will have big repercautions and must be taken with big care.

In the meantime I think the reduction of colonyship maintainance can balance it a bit.
