I would refrain from using people considering some of them may (become) controversial or are controversial depending on a country, there will never be agreement on someone who is not controversial at all and after all each country can use them on their coins if they feel the urge.

The birds idea is good, I like:

B - nice realistic

D/I/J - don't like vertical design (though I like colorful birds in J)

H - the most beautiful work of art, it would be my choice

Btw. why not use more designs at same time? I like Hong Kong approach to currency design (multiple commercial banks issue the banknotes under government regulation, three authorized banks—HSBC, Standard Chartered Bank, and Bank of China—design and print their own notes for daily use, while the government issues coins and the $10 note).

And very controversial idea, but this would be more suitable for national currency and not for eurozone - use banknotes as ad space companies can purchase, but it would have to be very very very costly space for country's budget to benefit from this. Though I like the idea of paying Pepsi with Coca Cola banknote.
