This is certainly not the correct way to proceed. Because of the RF230 chip, you cannot transmit more than 127 bytes total in one packet, including all the header data and CRC. Moreover, the longer your packet is, the more likely that you will run into collisions and data corruption, but maybe this is not an issue in practice, I have not tried. I would suggest you to use the default settings and build a multi-packet protocol on top of that to download or upload arbitrary length datasets. Search the mailing list archives, I cannot give you pointer on how to do this. But I am sure such projects exist for T2 and are platform independent.
