You can get down to 42 if that would work for you, well 45 actually unless you can use an oval chainring

Not to forget the additional weight (which is not neglectible) and the awkwardness of dealing with three different shifters for you then 12 possible gears. Technically sound, but heavy and expensive and hard to use (in combination with a six speed).

You already have two other bikes. Use them when you need the extra gearing. The Brompton is designed as a city/commuter bike, with the added side benefit its portability means you can chuck it in a train or plane to do some touring in faraway places. The compromise is the gearing, but for 99% of users that's more than adequate, plus has an advantage in that you see more of the countryside at the leisurely pace the Brompton enforces. I use the Brompton for mundane day-to-day stuff, plus the occasional holiday that involve aircraft, otherwise it's the 21 speed tourer for me.
One thing worth considering is what effect these mods have on the value of the bike if you want to sell it. I can't help feeling that the aforementioned 99% would want the Brompton as original as possible. After all, it is the iconic folding bike.

I'm somewhat loath to spend loads of addl $$$ on an already expensive bike.

2-speed Brompton
A few years ago I purchased a 2-speed Brompton myself. It’s great for commuting in the city because the 2-speed is low maintenance and simple to use. And with the reduced gearing can climb most hills that are common in the city.
If I was going to do touring or long distance riding I’d most likely want around 8 gears or more on my folder.

So here it is with T Bag loaded on a 45 mi mixed surface ride. So far quite excellent!
Going to get a standard Sugino 39T ring.

Very well founded argument, I'm impressed. So - according to you - a Schlumpf drive weights nothing, costs nothing and dealing with three different shifters to get a straight line of gears is as easy as using a single shifter for the same purpose? Good to hear. Where can I claim my free Schlumpf-drive?
