Ya dropping down to an 18" or even a 17" wheel would be fine. The tires get cheaper! I dropped to a 17".
stock offset is +19. so stay around a +12 at minimum and you should be happy with the "stance" or lack thereof.
With a level you should be able to fit a 33x12.5 tire..and that'll give you plenty of options. Toyo, Nitto, General, Federal, MIckey Thompson... all have off road tires in these sizes
