You are not booting from NAND, are you? In that case you would overwrite
the bootloader partition here.

The partitions come from the device tree. You're best off changing them
there and recompiling. This would be the gpmi node in
arch/arm/dts/imx6qdl-phytec-pfla02.dtsi.
There is a chance to do this from the commandline without recompiling,
but actually trying it seems awkward. You first have to delete the
partitions one by one:
delpart nand0.barebox
delpart nand0.barebox-environment
delpart nand0.oftree
delpart nand0.kernel
delpart nand0.root
Then add them again with the script you created. Note that the kernel
also takes the partitions from the device tree, so depending which
device tree you use you might end up with the original partitions.
