Another thought, Vic ... If the approach I suggested earlier results in a large, cumbersome or expensive packaging job for you, the easiest thing may be to redesign the attenuator using a larger number of lower wattage resistors. This would distribute the heat better and could result in a smaller final package with a lot less effort on your part.
