good idea. AGS uses 102113 and I use an override to manage this 
projection issue. eg

             Ext.override(OpenLayers.Layer.WMS, {
                 getFullRequestString:function(newParams, altUrl) {
                     var projectionCode = this.map.getProjection();
                     if (this.url == null) isAGS ==0;
                     else var isAGS = this.url.search(/arcgis/);
                     if((projectionCode == 'EPSG:900913') && (isAGS >=0)) {
                         this.params.SRS = 'EPSG:102113';
                     } else {
                         this.params.SRS = (projectionCode == "none") ? 
null : projectionCode;
                     }

                     return 
OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(
                                                                 this, 
arguments);
                 }
             });
