I have a friend who rides a Brompton who is at least the size you quoted
earlier - he's around 6ft5, and, I guess, 15stone. He rides it a lot on
road, with luggage/shopping on the bike. Has been known to take it up an
alpine col to annoy the local road-racers

Don't know the reasons, but the rear of the Brompton is quite narrow, so the
newer hubs are too wide.
There was an online PDF article about fitting a 2-speed gear (not using the
standard Brompton cog ratios) to the 5-speed Sturmey Archer hub (now back in
production), to extend the gear range. I think the range ended up around
300%, ending up as effectively a 7-speed due to the overlap of ratios. The
argument for this arrangement was a mixture of weight and cost; considerably
lighter and cheaper than a Rohloff conversion. I cannot remember the URL.

Might work nicely.
