No. It canīt be - MG4 has no developers substances incorporated in the emulsion. They stopped it with MG3 when they realised some problems, like long term storage (the papers deteriorate faster... they build up fog and get soft in terms of gradation).

So far I have used only one paper of this type - Fomaspeed Variant 3. It is much faster that MG4, it gets very soft after 2 years of storage and an undeveloped piece blackens within a few hours if exposed to sunlight.
BTW - a very nice paper.
