Is it possible to edit the DPA file or reverse engineer if there is no map source project available?

A DPA is basically a compiled map.  I'm not aware of any way of decompiling a map.  I've sometimes been able to pull compiled maps up into an editor and retrieve adapter settings (e.g. mdq file names for DbLookup), but you can't create a map source from a compiled map.

Yes.  The result of compiling when the execution default is Datapower, is an XML file.

This XML file can be imported with the mimport.exe command line utility or with the Design Studio.

The Typetrees can be recreated by importing the .MTS files created by the compile process, again using command line (timport.exe) or Design Studio.
