Hi Ally
I did this in the Cairn Toul to Braeriach direction on Midsummer's Day in 2011, in mist and rain. The route was the WH one, but omitting Devil's Point due to the conditions. It was only my second Munro walk (but not only my second mountain walk!) and I managed it in a day. So it's doable if you've got decent hill fitness.
Are you thinking of doing the Walk Highlands route in reverse? The main thing that strikes me about your reason for starting with Braeriach is to be "off the mountain" when you get to Corrour Bothy. In reality you'll have come down from the second highest plateau in Britain, but you'll still be on rugged mountain terrain, with two demanding mountain passes to cross: the Lairig Ghru and the Chalamain Gap. The former pass involves a long route on rough ground which takes you back over 800 metres above sea level. The latter is shorter, but choked with very large boulders, some of which are unstable, and would be tricky to negotiate in the dark. Whichever way round you went, if you used the WH route, you would be crossing the Chalamain Gap late in the day when you're tired, but still need maximum concentration and preferably daylight.
In principle, there's no reason why this route cannot be tackled either way round. When I did it, my own preference was to get over the Lairig Ghru first and reach Corrour Bothy, at which point I was able to decide if I had time to get back over the Munro summits. Good luck, and I hope you get decent conditions.
