You could both end up in serious legal trouble and expense.
Dubia aren't magical. They are no better than discoids which are legal- they are very similar insects and both make excellent feeders, both have simliar body size, both do not climb smooth surfaces, both have the same care and breeding, both have the same diet, and both reproduce at similar rates.
Honestly, other than word of mouth making dubia more popular after enough people tried them as their first feeder roach and liked them, there is no reason dubia are so popular. If the coin had flipped tails instad of heads, and that first enthusiastic user of mid-sized non-climbing roaches had picked discoids and then started recommending them all over the internet and started the chain reaction with discoids instead of dubia, discoids would be the "popular" roach. There really isn't that much difference between the two species.
Don't do something stupid for no good reason- get discoids.
