No. chances for success are slim even if all three are small. As they mature and get bigger they will get aggressive. A Kole Tang would be okay ...a small yellow or purple could SURVIVE for a brief period in a four foot tank. They require at least 6 feet of swimming space. Also, as adilts three ADULT tangs in a 180 could explode into aggression one day.
I would never suggest placing three tangs in a 70 as they do not stay small for long...so then what?
Also, when do you know it is time to remove them to a suitable home? Once they are sick or stressed due to living in cramped quarters?...... it could be too late.
If you are not prepared to house the animals through adulthood or have a plan to move them...you should not do this.
Finally, tangs are big poopers...even small ones...too intorduce three at the same time could cause water parameter issues due to a bioload that cannot handle the increased wastes in such a short period...meaning all three could get sick and die...or your system can start a mini cycle leading to death. Yes, you can add so,e magic potions to try and boost your bio-filter but how do you know the bacteria is alive inside the bottle? Shelf life, inappropriate transport, etc can render this stuff ineffective.
Can you place three small tangs in a 70 at the same time? Yes but it COULD fail. Will they all get along and survive for any length of time...possibly but odds are against you.
What is you long-term or short-term plan for these animals? Do you want to keep them for years or months? Ask yourself these questions and arrive at you own conclusions based on research.
There are no absolutes in this hobby...but there are certain guidelines that if followed will increase the odds for success. If followed both you and your animals will be happier.
I am not saying never or can't...I am simply trying to help you succeed. I have tried what yor are asking...been in the hobby for 30 plus years and followed the advice of the lfs. If you so some research you will see that your y=system is not bif enough. You can either not make the mistke I made...or try it and see what happens. Outcome is predictable though.
You will get others that will tell you it is okay.
JMO and just trying to help.
