If you want serious answer, it looks like there is enough room under it to slip in a piece of wax paper. If that is true, then you can repair in place.
Rough it up with a chisel or similar, sand the top with really rough sandpaper, slip the wax under, then fill with a mix of chopped glass and resin. should bond okay and be sandable to the proper shape. The closer you get it to the original shape and thickness, the less sanding and re-glassing you will have to do.
When Dave sees this, he'll probably say I'm nuts and to remove the console and do it right.
