BC.. well, can be actually good on Corki - CDR, HP, AD - all good. And he can stack it in 1-2 second on 3+ targets, if they are  in E(main target will be anyway). So (almost) like LW in terms of armor penetration - and, actually, can be a good suplement for survivability(with triforce and GA it's 650 bonus hp and 50 armor/m.res, which make you a lot harder to burst down. And W will be up more often to fly away from harm).

IBG.. well, just no. If you really-really want that slow - better take mallet instead of GA(like IE, BT, triforce, BC, mallet) - at least it give AD and protect from magic damage too - if only by giving more pure hp(magic damage more often come in burst, and burst, not sustained damage, is danger for ADC).
