What about making additional tech levels for the colonization components. Remember SE3 and the incremental colony types - I think they were 1M, 10M, and 100M IIRC. Maybe you could do something like that - Rock I only allows your atmosphere type, Rock II gives 1 dome, Rock III gives 2 domes, etc. I don't do a whole lot of modding so I don't know if this is even possible - probably has to have some hard coding somewhere - maybe an idea for SE5??

ANyways, I like the idea - more variety is good as long as it doesn't sacrifice gameplay...
