CC2630: Placing OS components like SYSBIOS at known flash locations

I'm writing for an application where using SYSBIOS in ROM isn't possible so I have to place a lot in flash. Unfortunately this has put me in a difficult situation resource wise, at the moment I do not have enough space to write my application in a way that can be updated over-the-air. A major factor is how much space is being taken by SYSBIOS and other IAR components.

I started by placing the stack image to the end of flash and applications will always reference it, that helped but wasn't enough. Looking at the map file:

Since these libraries aren't being actively developed anymore I think I could save some space by placing some of these outside my application. Is there any way to move some of this code to a fixed location in flash?
