First I think you need to let cad create the sister files in the projection of choice this maybe able to be done in batch process, then move all the original rasters to a folder and store them with the new sister files in the projection of choice...

Now you should be able to bulk attach the rasters using the sister files and then tell cad to convert all the rasters to GEOTiff...

otherwise get GIS person to do it in map info or Esri....

There are Free tools around google GDAL, its pretty tricky to set up uses python and a bunch of scripts , but one script I have used was to redifine or reproject tiles to a new datum and join all neighbouring tiles into one ECW geo refed no sister file and one tile nowdays loads pretty quick, twenty years ago we had to do lots of tiles because video card and pc ram couldnt handle it... I regularly load a 6 gb airphoto raster 300mm resolution in just 2 -3 seconds over a network and yes msnt did cache it but it still loaded damn fast...

also google tile or raster stitcher I used a free one ages ago sorry dont have it any more
