No such a tool exists yet AFAIK. Often the needs is the other way around and Delphi is admittedly still a competitor. If such a tool exists, it should be written for Delphi instead of Lazarus. Language-wise, newer Delphi also introduces some breaking changes although FPC catches up some with compiler directives. Writing a newer Delphi compatible Lazarus project is harder then, and you don't really get something from porting Lazarus projects, as Lazarus supports many more platforms both as a host and a target than even the latest Delphi.
