Hey Duster.The resistor will work fine for what you intend it to do function wise.I always try to over spec resistors by 3 to 4 times for dissipation.Their dissipation ratings go down as the ambient temperatures go up.Think sealed chassis.Pretty common practice as far as resistors go.
If you already have the 50k's you can put two in series to make a 100k with double the dissipation(1 watt). It will still serve the same purpose.
