I agree that in theory this would be a good idea; MadRussian's mods do, imo, significantly improve the visual aspect of the game (though as Gunner24 rightly says, the vanilla graphics are more than acceptable). However, if the issue is presenting to the wider public the best visual presentation of the game (and getting new recruits), then this is surely possible as things stand. 'We' can post screen shots/videos using MR's mods, and if JMM and MR agree, they can also be posted here.
Off the top of my head, I cannot think of too many developers/publishers who have 3rd party mods incorporated into their games as official patches/addons. I'm certainly not an expert on this, but I imagine that even if JMM and MR agreed to this, JMM would have to test the sofware going out in his (companies) name. I don't for one minute doubt that there would be no problems, but legally this may be a requirement? If this was the case then the time spent may not be worth the gains: just a thought.
