There shouldn’t be any problem with this planting arrangement. You’ll just to watch that all the plants aren’t getting too much water—or too little. Spider plants are fairly expressive when it comes to showing their desire for water, so you should be able to tell when they’re thirsty (they’ll look a little wilted). As for the pot within a pot: it would be best to use a clay pot or a pot made of some other breathable material, as plastic may hold in too much moisture if you’re not careful. Or, simply be diligent in checking the inner pot to make sure that it’s dried out sufficiently before watering again.
