PS 3 exclusive engines can generally be ported (extremely hand optimised parts will be harder), but there are some issues if you would like to use such an engine as a 360 engine for running the specific PS3 game.
For example more and more stuff has been moved to the Cell's SPUs for such engines, an issue will be for the 360 CPU to process all the code at acceptable speed. Also the PS3 has a seperate bus for graphics memory and high speed main memory (which can be used for the GPU to double bandwidth), that's a significant difference compared to the unified memory approach on a single bus combined with limited EDRAM (will result to tiling). Another example would be the usage of Blu-Ray (constant predictable data delivery)/harddrive (high speed compared to Blu-Ray/DVD reading) optimised streaming, a 360 game would need different care for best optimised streaming (no default harddrive in older model, varying read speed on the disc). Blu-Ray capacity => could result into mass data duplication spanning several 6.8 GB 360 disc, disc swapping routines, considerations, etc, etc.
I you can, ask the perspective of your professor with regard to such points.
