The other option is forget the lists, forget points and balance, play the rules that you like the best and put whatever you like on the table armed with what ever you like with what ever special rules (or lack of) make sense to you. Write it as a scenario so you don't have some idiot turn up with his homebrew uber unit of death.
Keep the feel for 3rd, which is what we all miss, by adding the fluff even use the old lists to guide you. Alternatively just give 3rd a go once and see if it is all you remember. To be honest I never really read a rule book fully after 3rd just sort of added bits of rules here and there, they all got jumbled up. Throw away the rules! Who needs them, just make it up.
