    I've found a 270ft structure that is surrounded at the moment by Scaffolding. making access quite easy.
    The structure is narrower at the top, causing the scaffolding to be 'stepped' in slightly (approx 4-5 feet at 40-50 foot high increments).

    Does it sound reasonable to launch from the corner (PCA), and clear the slight outcrop below. Does the scaffold raise any other issues? Would it make more sense to freefall, giving more clearance? Landing area is reasonable.

    It sounds like crap!

    Here are the number in a theoretical and way too optimistic fashion:

    5' underhang per shelf
    30' overall underhang.
    45' clearance to next shelf.
    6 shelves at 270' overall.


    9' Bridal
    10' Suspension lines and canopy.
    5'-6" Torso and lower body length.
    ----------------------------------
    24'-6" before canopy starts to inflate.


    15' to 20' for canopy inflation
    -----------------------------------
    44'-6" shortest possible opening distance.


    45' per shelf.
    -----------------------------------
    You have 6" at the best case left over, if you have no more than a 10 degree off heading either direction.

    Please note, these are rough numbers by not knowing or seeing this object. I calculated these figures by the numbers you gave me.
