I suggest you build it exactly as you want, and see how it works. Our internet guesswork will not beat the accuracy and usefulness from an actual test of the system.

When you do, think of every step you can to minimize the drag on air flow. Maybe use 6” hard lines to connect from your drum to your blower motor suction. Come out of the side of the 30g drum, up high near the top, rather than straight up out of the top, so an elbow is eliminated. Use 45-degree bends when possible, instead of 90-deg. And so on.

I believe this question is about reducing internal drag, not about any pressure differentials that might result simply from the drum being higher above the motor. I bet that almost every DC system in use could be redone to cut some of the internal drag. If you make sure your whole system is well designed, the effect off this plan for drum placement should be negligent, and maybe none.
