Memory available on Quatix 3

Here's question that will reveal the depth (or lack thereof) of my knowledge!

Is there any chance that the Quatix 3 will be upgraded to provide me with the 122kB that I enjoy on the VA-HR?

Is it "just" a VM upgrade to CIQ2 (or 3?) or is there some real hardware limitation?

My app uses 100 kB (max), so will require some serious re-engineering to fit into 56kB, but I really would like to be able to offer it to the Quatix 3 community.

Maybe such speculation is pie-in-the-sky since the Quatix 5 is already being spruiked.
