Yeah, Oulu works just fine. The only downside that unit has is basically no offensive BB, but the high point is that Oulu has a higher def buff on it's SBB. However, most of the time you would be casting BB. I think as long as you have Oulu sphere frogged with Evil Shard and maybe Dandelga but I don't see it working as great like Darvanshel.

Both units have same fill rate at 22 BC for BB so they are both even in that. I know that the Evil Shard would be great to passively fill Oulu's BB gauge by 3 BC a turn. Dandelga is questionable since it increases ATK and HP but also a nifty BB gauge increase. Together with Evil Shard, it grants 5 BC a turn.
