Of course that what I said doesn't mean that some parts of the WeatherDuino system will not evolve at some point in the future, but backward compatibility with existing systems should always be a concern, and assured as much as possible.
For special situations, the RF coverage range of the used 433Mhz modules can be greatly expanded using RF amplifiers. Recently I tested one of those amps, which can easily reach 1Km (3Km according to manufacturer) in open space. Doing this with one way RF links, it's easier.
I'm pleased that you appreciate the WeatherDuino software, it represent countless hours of work, and it's free to everyone.
I think that will not be too hard adapt the code to use the NRF24 module. As it uses SPI, you may need to change some pins currently used. Possibly (I'm not sure) the Arduino library for the NRF24 and the required changes will increase the code size beyond the Arduino Nano limit, but as you intend to use an atmega644, this shouldn't be a problem.
