If after my last distribution, say on the fourth year of tuition I want to consolidate all four years of loans into one, can I do so and still be eligible for the loan to be discharged in the event of my death? So, for example I want to consolidate four years of loans into one 30 year loan, I would want to do so but not forfeit the condition that if I were to die that this loan would be discharged, or is there any sort of conditions based on the loan being discharged in the event of death?

It is actually up to the new lender. I believe that the previous discharge benefits still apply, but I would check with the consolidation lender.
