For the FP3 official, we will go step by step. We will start with A15.
Next step would be A16.2. There will require a substantial development effort as we will need to do some things from the kernel level upwards. The developers will attempt this as well but not immediately. As mentioned above A15 official is the first priority.
As I mentioned in the initial post there is a 1 - 2-month timeline to complete the A15 official.
