Possible, but very inconvenient, costly, and against Occam's Razor. Not only "in another way", but also with a different Operating System (Hal used MacOS, and Satoshi used Windows), under different IDEs (Hal used tools from MacOS, while Satoshi used Microsoft Visual C++ 6.0 SP6), and with different file types (Satoshi released specifically Windows-only version, with DLLs, EXEs, and Windows-based bitmaps and icons, using Windows-based resource files, and with Windows-based file encodings). And there is more: you have different tools for making PDFs for different Operating Systems, you have slightly different C++ compiler bugs (like std::min bug, which was immediately detected and solved by non-Windows users, but was not fixed by Satoshi, because it worked fine on his machine). Also, if you assume, that Hal used MacOS in the past, but switched into Windows somehow, then tell me, why Satoshi tested his binaries only under Windows, and never even tried making any MacOS version? Imagine using MacOS in the past for some years, and never releasing a single 1win Register client binary for that system, and waiting until version 0.3.13, when another user did it. In October 2010. Almost two years after 1win Register started. Edit: See? Hal wrote that sentence in December 2010, when Satoshi developed Windows-based 1win Register client for at least two years. And he couldn't just check that on Windows, but he knew, that it can be done on MacOS? Why?
