The idea of loading all layers from a base project file was discussed here: http://lists.osgeo.org/pipermail/qgis-user/2010-September/009548.html I think your idea of being able to select a subset of layers is cool and could deal with the issue of rasters in a different CRS. The selection dialog could mark those raster layers as being unavailable.
