Default cooling AG with ice?

So I've been searching and couldn't find the answer I was looking for. Maybe I wasn't using the right search criteria. Here's my question.

Is it feasible to boil your wort down to 4.5 to 5 gallons, from 7 to 9 gallons, before doing your hop additions? This way i could cool it off with ice instead of other methods. Would or could this scorch the wort? Would this just take way too long? Or is there something else?

And yes for the time being I'm being cheap and don't want to buy/make a chiller. If this isn't something with pursuing I'll settle on an bath and time.

In theory it could, but it will take a long time and alot of ice. If you submerge in an ice bath, make sure you stir regularly with a sterized spoon. Yo might better off eventually saving up for a wort chiller. You can make your own or buy one. I bought mine from beverage factory shipped for under $60.

We cooled all grain 5.5 gallon batches with ice bath for a while. Takes 50 to 60 lbs of ice to cool it down in a reasonable amount of time

Well we got by with 40 lbs, but the place right by the house sells 20 lb bags for $1.50 so it was worth it just to get a little extra

That's alot cheaper than NJ I suppose. We would have spent at least triple for that amount of ice. Frozen water does not come cheap in the garden state, actually nothing does.

A Wort Chiller is a real time saver, and in the end, a lot less money than constantly buying ice. We went the ice bath at first but we moved to the IC Type Wort Chiller fairly quickly because of all the money we were spending on ice. Even worse, we would not get enough and have to run to the store mid brew. We have since moved to bigger batches (22 gallons normally) and have a Plate Chiller and Pumps. Going form ICE Bath to IC was a great step, but we do like the plate chiller as it is fast and we can normally have the Wort in our Stout Conical in less than 30 minutes (incluing Whirlpooling) at about 65 degrees. We do use some ice to chill some water in the summer to get to 65, but in the winter we do not need any ice.

I do extract right now. At the end of my boil I have about 3 gallons. I can cool it fast enough for me with just 1 gallon ice, cold water bath (no ice) and top off with cold tap water.

About how long does it take to boil off about 2 gallons? Just curious. Not about accuracy right now.

Why would you boil any extra off to start ? You could just start with 2 less gallons and then add your frozen top off just like you do with extract.
