Hi, Cingatronix. Welcome to The Raven.
Two versions of Lal's fate were filmed*
but in the final movie you can see him crawling away to safety. Oh, and the Monkey Man from "Raiders" didn't die, either.

Anyway, no, Lao Che should not come back because that would be 3 movies in a row with returning characters. I'd personally prefer all new ones (which is one of the reasons I love "Doom" so much) though, as Pale Horse suggested, a nod to Lao Che Air Freight would be cool.
