Navigating Bow roundabout/flyover

I think the Bow flyover situation is really simple to resolve (I cycle this most days, so bear with me here):

1) 99% peds and cyclists are going east/west.
2) Traffic is doing all directions, but west to east traffic over the flyover is minimal. East to west is mixed, but this is already one lane anyway.
3) There is NO pedestrian crossing that actually allows peds to safely go east/west across the blasted roundabout (unless you are a professional sprinter).

So my view is this - get the bikes and peds away from the roundabout and use the flyover...
a) On the West -> East side of the flyover, take one whole lane and convert into cheap ped lane + segregated bike lane. Put ped/cycle crossing points at either end of the flyover. I had a look at TFL's first attempt at this, but it was stupid as it forced all cyclists to use the ped/cycle crossing to access the segregated part... daft and slow.
b) On the East -> West side, rinse and repeat, but make this a "full cycle lane only" affair and move the road lane out into the hashed section. Add cycle crossing lights at the east side so bikes can easily get across to the flyover.

• Note, none of this impacts the bow roundabout... so any excuses about impact on traffic flow can be ignored here...
  
  

For the rest of the CS2 between Aldgate/Bow Flyover, I would make the bus lanes 24hrs mandatory Bike/Taxi/Bus only. No other traffic allowed. And paint the whole lot blue + remove the rights for car parking outside rush hour...

• For all bus stops, make sure there is enough space for bikes to go round the outside the bus and stay within the restricted lane.

• After that, then we are into pavement reduction/segregated cycle lanes. But my issue is that the whole route is so busy (with junctions, tight bridges) that it would make the whole thing too complicated to use without making it more of a nodder fest than it already is.

That's my thoughts...
