While the Captain Sim Weather Radar isn't perfect, at the time of writing my previous posts it was the only Weather Radar, that I know of, that showed something close to what the weather was actually like. Of course you now have the REX, Active Sky, and a few other noted Weather Radars available that show the weather more realistic than the Captain Sim Weather Radar.

If you want to replace the 727WXR screen with a different one, you can change it in the panel.cfg by replace the gauge name, shown in bold below.

727-100:

[VCockpit11]
size_mm=1024,1024
pixel_size=1024,1024
texture=$WXSP
background_color=0,0,0
gauge00=Captain_Sim.p721.wxr!wr_display, 0, 500, 305, 225

727-100F/200/200F:

[VCockpit11]
size_mm=1024,1024
pixel_size=1024,1024
texture=$WXSP
background_color=0,0,0
gauge00=..\..\CS_B727-100\panel\Captain_Sim.p721.wxr!wr_display, 0, 500, 305, 225

Note. I still like the CS Weather Radar, and even though it might not be accurate, it still shows the weather to be something like it is in FSX, FSX-SE, and P3D. ;)
