The N. rustica will start to wilt a little when it's time to slop some water in the pots, so it's sort of an "indicator" that keeps it's big brothers from getting over-watered.
I'd say slap in whatever ya want & see how it goes, doubling up on real estate is a good way to get the most out of a limited amount of planting space.

Yes, indicator plants is a good horticultural practice and getting the most out of your acreage is just plain efficiency. I have a potted Artemisia absinthium that sits among some of my plant stock -- when it starts wilting all the others will need water in a day's time.

Earthworms are nematodes. One of the varieties of harmful nematodes is known to ignore marigold roots but this does not keep them from attacking neighboring plants. Further, marigolds attract a host of other pests. You would be better off applying a little natural soil sulfur prior to planting your tomatoes. For other people who use water solubles, the sulfur is typically included.
