Remember, the vendor only provided an ASCII-ized firmware because our system required it that way, not because that's the preferred form. * in-tree firmwares should be stored in one or more binary files in the tree, not in C source code or .ihex files. * when firmware is stored as binary blob, it is easier for (1) vendor to replace, (2) developer/user to compare/verify using sha1, (3) does not require a C compiler or binutils to unpack Thus, if you are going to be touching the in-tree firmwares at all, it doesn't make sense to convert from C source to any format other than native binary.
