The only way to get Spartans like the Spartan 2's would be either go through the trials again or in the future one or two of the Spartans settle down and have offspring which then decides to join the military.
I think by the rule in Biology that parents do not pass down acquired traits to their offspring would mean this wouldn't work. Then again, I'm sure someone here is better qualified in Biological sciences than me and could tell me I'm missing something.
