A high power, temperature controlled, thin tip soldering iron is very recommended, but it doesn't guarantee a 100% success... anyway, it seems that you have nothing to loose.

Good idea. Thank you. And the number of permutations for the order of the three chips is only three factorial 3!=6. I will try that.
