Perhaps consider one way road access with some parking. Southbourne grove more popular than Boscombe because of this I think. Free short term parking generates passing trade.
I say this being relatively anti car but you need some balance and a one way bit with speed reduction and bicycles able to use as well would be good I think.
Anyway to encourage shop facades to look like the beautiful elevations of the 1st and second floors but I know that is a dream.
Keep it simple you will not get the full funding.
Liked the Boscombe station idea and close pokesdown. Bridge negates need for lift, buses can easiky interconnect, football club gets station right next to it. Win win
