It's known as Resident Evil outside of Japan.
It should be more than possible to create the enemies that have AI Capable of using a multitude of weaponry.
Melee Weapons (like Swords, Fists, Etc..) will probably need to be setup using scripts, and alot of effort for creating the animations to accompany them.
This said Onimusha and Resident Evil Style games are not really what the FPSC is designed to create. It would be possible with heavy modification. From what I understand the Engine outputs to DarkBASIC Professional, so if you need to you could export the game in an FPS Style, then modify the code in order to deal with the new weapon types and style of gameplay.
Game movies will probably be reserved for entering the game itself, but unlikely for between levels. CutScene levels will be possible through scripting.
You can again change this if you export the code to DarkBASIC Professional, then put in the cut-scenes in key areas yourself.
Nothing really will be unobtainable. I doubt that either thing you desire will be possible purely using FPSC though.
