The possiblity of only “flash” framework of 4.0？

For my phone has no vendor support of Android 4.0 upgrade，so I cannot make a new kernel image for missing Kernel driver modules especially radio related. But I know that Android framework has clean interfaces between hardware via HAL. So ，can I only port those 4.0 HAL from source scratch to 2.3 kernel driver interface based （the kernel version is 2.6.38）to enable 4.0 framework directly working on it ？thanks
