Can I substitute m30s for morphine in the 5 drug mixture?

[enditplz]

I'm not finding a lot of conclusive information on the 5 drug mixture on if this substitute would work. I've found sources for 3 of the drugs and I'm missing morphine and phenobarbital. I'm wondering if I get some m30s off the DNM that are hopefully laced with fentanyl, skip the pheno, and follow the rest of the regime, would this be enough to CTB? Could I CTB off of the m30s alone? I keep reading reports of people accidentally dying from fentanyl laced pills, so if I down like 20 pills at once, would that be enough?
