I don't know what their licensing deals look like, but they should sell subscriptions in foreign countries.
I pay $5cad/mo to get ad free access to the CBC catalog. I would gladly pay the same or even double for the BBC catalog or iPlayer (whatever its called).
They don't even offer that in the UK. Madness, imo, but true.
(iPlayer is free if you're a licence fee payer, but it's nothing close to the full back catalog, it's more like an 'aired recently' DVR with a tuner for every channel. Wouldn't at all be surprised if it's not even everything current though.)
(The Britbox joint venture with ITV was arguably closer to that, but still not, a curated collection.)
