That would be my go-to as well. The classic 5/8/x 'Mechs are great, versatile units. Personally, I would go for Griffin, Shadow Hawk, Wolverine and Dervish, but there are other possibilities, too: Quickdraw (for a commander), Starslayer, Lynx, Gladiator or Valkyrie (as a very light option) or Trebuchet 5J would make good additions up to the Clan Invasion era.
