ferrule replacement gone wrong

I posted this issue in the ask the cue maker section and pretty much got the opinion that this was not the way to replace a ferrule. So, as players, what do you think is a fair way to deal with this issue.

The shaft can not be replaced because it goes to a custom cue from a famous cue maker who is dead. I don't play with shafts that are smaller than 13mm.

Story is, I took this shaft in to have the ferrule replace and it is at this point now.

As far as due diligence, this shop has done the best work in town over the last number of years. This time a different person worked on the shaft. I figured if he worked there, he knew what he was doing.

The person that did this to my shaft is a person I have known for about 40 years. I thought we were friends, hahaha. First question I will ask him when we talk again is if something happened where he does not like me anymore, hahaha

I figure the answer is to cut down the shaved part of the shaft and put on a ferrule.
Then remove the ring work from the joint of the shaft and put in a spacer. I have seen nice cues with a different wood used on the first inch or two between the joint ring and the shaft wood. The cue has an ebony forearm so an ebony spacer would actually look very nice. Then we can only hope it plays as well as it did before.

What do you think about that idea?

Also, I am a business owner of a number of companies. I want a chance to make things right with an unhappy customer but some customers are a##holes.

So, I came to azbilliards for a second opinion. I did not want to be an a@@hole but your comments back up my first impression. So I don't think I will be out of line asking for him to make a major effort to make this right.
