Absolutely you can.
I suggest you find out the exact comp size that the Film Out House uses before you start.
Its then a simple matter to create seq tiff / tga from AEFX that they can load and use for the process.
I'm less conversant with After Effects, but I don't think Premiere can handle those resolutions by itself. As far as I know, they only become available with the RED plug-in.
Good to know.
