Doesn't sound too bad if the body is in decent shape. If you are swapping to a 208 case, put a 700R4 in it too. If not, just put the part time kit in the 203 case and you are good to go. That is a lot cheaper. I don't think the terms "73 Blazer" and "easy on gas" will be used together too often, though.
