Converting a Brompton from 3 to 6 Speed

I've owned Bromptons since 2014, with 3 bikes at my max. All of the bikes are 2014 Bromptons.

Since then I've collected a TON of spare parts (both original and third party), and I'm hoping I will have most of the parts necessary for the upgrade.

Here is a rough list of parts I think I might need for the upgrade, most of which I should have buried somewhere:

1. 2-spd shifter (yes)
2. BWR Hub wheel (yes)
3. 2/6-spd Chain tensioner (yes)
4. Chain pusher (likely)
5. Dog leg (likely)
6. 3/32" Chain (likely)
7. Shifter cables (likely)
8. Screws (maybe)

Am I missing anything else? My BWR Hub wheel has lain unused for more than 1.5 years, kept indoors but I wonder if it's going to work okay after installing.

Any advice would be appreciated. Thanks.
