Hey @ReloKai! Welcome to the forums!
Unfortunately I can’t really help you that much with this because… You haven’t stated what the trouble is with Down/In Front! 
What I will say is typically for a wall run it’s all illusion, you would have an animation playing right-side-up for it, and if you don’t want to do that you should simply rotate the static mesh and its children, not the entire actor because that throws off relative rotations and things get really dicey in the mathematics department!
