Roseapple pi image needed

I would like to request an image of mate 16.04 for the roseapple pi computer. This machine has 2GB ram and may run faster than the raspberry pi 3.
Ubuntu mate seems to run well on the pi 3 and I am wondering if it would be possible to compile my own image? I would start with a test version for the pi 3 and then adapt it for the roseapple.
Alternatively, is it possible to upgrade a debian image for the roseapple to mate 16.04?
Thanks, David.

This link seems to cover the topic.

So far the upgrade process from 15.10 hasn’t worked.
