I would say just let us have what ActiveSky was able to provide for FS)/FSX and I would be willing to bet almost everyone would be happy.
I know I was very happy with the results I was able to get between ActiveSky and FSUIPC.
Quite a few times I would literally sit on the virtual ramp at KONT while working on a cfg file etc during the gestation of the different Connie versions and when it started to rain on my real window it usually would do so in FS as well a few minutes later 
The same goes for the winds etc…but here FSUIPC did modify the directional changes because occasionally there would be 180° swings that did not happen in the real METARs.
