CCP (Credit Corp) or LFS (Latitude) spring to mind, though LFS have a suspension to sort out first.... CCP has a current market cap of 1.14B and LFS 1.25B. A merger would see a market cap of minimum 1.5 - 1.6 Billion, this would get them included in the ASX200 index and bring a tide of index buying with it. An acquisition with a capital raise would likely see the market cap >1.5-1.6B and a nice buffer to stay in the ASX200, any transaction would likely have a capital raise component as this would assist in releasing the franking credits (or newco may be too leveraged).

Index buying aside. Synergies would come from a shared balance sheet (better financing rates) & streamlined corporate structure. The real kicker for CCP would be index inclusion.
