I wanted to bump this and see if anyone would have a spare few minutes
to help me out with this. I know it's a needlessly complex situation,
but I'd really love to know how to resolve the specific issue, or
perhaps learn a better way to approach this in the future if I'm
shooting myself in the foot here.

Thanks again.
