I went ahead and replaced all the 4 rocks with the new meshes with unique statics so that rest of vvanderfell doesn't get affected like in Valenvaryon. 

I created new meshes in the CS for those four pointy rocks and using tes3cmd replaced corresponding rocks with the new mesh only in the cells modified by MRM, i'e in red mountain. So now those pointy rocks only appear in red mountain.

Also included is GDR patch for MRM. I used BTB's edited plugin to create the patch as it eliminates many errors.

UPDATE : 
	* Moved the lower entrance out of Dagoth Ur above ground
	* Moved the rock blocking Vemynal entrance
	* Corrected a few errors infornt of Odrosol and Vemynal
	
If you are updating from older version, then you might want to us the Updaters features in Wrye Mash. To avoid doubling.
