It really depends on what you want to consider Halo 3: ODST and just Halo 3. If you consider the multi-player disc that comes with the ODST package part of ODST, then yes, you can forge with it.
It will be the exact same forge as you are used to in Halo 3, with the exception of three new Mythic maps.
