That doesn't solve it at all. In fact, you can model that right now using scripting anyway. The player need not think a jot about managing his engine because if he screws it up he has a random chance anyway of getting a good one or screwed one, and if he's gets a screwed one he can just respawn anyway.
Unless the server mission can track an individual players treatment of an engine and store it for use in that mission or subsequent related missions then it won't work at all.
