You could always use something designed for 6 or 8 POB but limit the load to two.
Or what about the 285HP version of the 55 Series Baron? Again, limit the load to two.
Or use a turbocharged variant of whatever seems best. Or what about an aftermarket bolt-on turbo-normalised version if there isn't a turbocharged model offered. Turbo-normalised may remove some of the maintenance $$$ penalties compared to turbocharged eg reduced TBO etc
Depends on how much you're prepared to spend...
