32 bit replacement for Mega 2560?

Mega Replacement

Could this be a 32 bit replacement for the Mega 2560? It looks just like a 2560 but I do not know enough about these boards yet to tell if we could use these and would these be a good replacement if so?

So far my history in changing boards between different compatible ones isn’t as easy as it should be. I’d expect to spend a fair amount of time in the compiler to get it going. Most of the time it’s been doable, with the exception of a navspark board. But, it’s usually taken a fair amount of time to get going.
