You may be able to. That depends on the fish. The EBJD do tend to be more mellow. I have even seen severums with the normal JD's. I am fairly certain it works fairly often and I am certain there are times when it doesn't.
They wont die without sand. There are many worse situations you can put them in. It will be happier with sand and in a group, yes, but its not going to kill it and make it suffer. Altifrons are less group oriented anyhow if I am mistaking and I'm fairly certain that is what it is. That stocking may not last forever in a 55 either but again, I've seen worse. The stock can always be thinned as needed as I am sure these are not full grown adults yet.
