Possible, yes, but there are some problems with the simple approach.
The easy way would be to get the width height for the text box and the rectangle it needs to fit in with sourceRectAtTime(), then scale the text layer to fit the smaller dimension.
The problem is that you don't reflow anything this way, just shrink it, so it's not going to fit the rectangle nicely. You're going to get uneven, in many cases VERY uneven, margins at the top and bottom versus left and right.
Thanks I followed that link but my expressions knowledge is not good enough to modify if as needed and it creates a huge processing problem too which is not idea. So I did something slightly different and less fancier for now... and have put through a request to Adobe to include some formatting options in Premiere Pro for text boxes created on AE.
