I-864 is not only not required, it is not really acceptable as a substitute for I-134. So, that cannot help. However, information listed there might clarify more details (it has more details than I-134).
As I said above... Neither of these forms is required. The I-134 is nice to have. You can get by without either if you can show income or assets of your own (e.g. job letter, bank statements). I-864 is not the right form and should not be used for this purpose (but you might get away with using it as neither form is required).
If you are going to show someone else's job letter or bank statements then you should get an I-134 to go with it.
The interview letter we got specifically mentions that I-134 can be supplied "if necessary."
