Anybody installed a modified 3rd gear to a BWR hub?

The problem with the hills I have on my commute is they have an uphill immediately after them, so you need as much speed as possible going down, to make going up the other side much easier .

Id be interested to see if you can fit it without a new chain as I was advised you need 2 extra links (but im sure theres enough slack in as standard?)

I upgraded mine from a 6 speed to a 12 speed with a front derailleur, front double crank and a friction gear shipper. works a treat. lowest gear is 11". cost about £90 total.
