I doubt this :)
We tried to compile FPC itself with Delphi 4 and Delphi 5 and our experiences
were very bad:
First, it took a lot of time to work around the delphi compiler bugs, the
main problems were the unit interdependencies and the optimizer.

Secondly (if you get something running), the compiler compiled by delphi
is two times slower than a compiler compiled by FPC :).
Reasons:
- the Delphi heap manager is slow
- the optimizer was switched off for several units (see above)
- the Delphi register allocator is good when your using
   simple expressions while the FPC sources are full of
   rather complex expressions

So I don't think that it is easy to compile Lazarus with Delphi. Afaik
the Delphi IDE isn't written in Delphi either...
