All luggage is inspected at the airport by the United States Department of Agriculture. From their website, here is a partial list of items that can NOT be transported from Hawaii to the Mainland:

Items from Hawaii Not Permitted into the U.S. Mainland:
Berries of any kind, including coffee berries and sea grapes
Cactus plants or parts
Cotton and cotton bolls
Fresh flowers of gardenia, jade vine, and Mauna Loa
Fresh pulpy fruits and vegetables (except pineapple)
Kikania and fresh pandanus
Live insects and snails
Plants in soil
Seeds with pulp and fresh seed pods
Soil
Sugarcane
Swamp cabbage (unchoy)
Sweet potato (raw)

Looks like the prohibition on transporting soil is going to be the one that ruins your plans. Sorry.
