Addon to increase the number of buffs per row on UNIT FRAMES

[frostimus]

As title states, would like to know if there are any addons that increase the number of buffs/debuffs per row on UNIT FRAMES, not the player's.

This discontinued addon is basically what I'm looking for:

If there is no addon that does this while preserving the Blizzard UI, is it possible to update the aforementioned addon to work in WOTLK? Thanks.
