After playing Pendragon for a long time, we tried this recently with another BRP game we played over the Summer and it worked well. It reduces the amount of dice rolling and made combat more streamlined and did away with initiative/dex ranks altogether.
We did it pretty much full Pendragon style:
All actions declared before rolling any dice.
if you were unopposed, just make your action.
If you faced multiple opponents, you could divide your weapon skill among your opponents as desired and make opposed rolls against all you faced.
I enjoyed that there was less dice rolling in general and I am strongly considering doing it for a Magic World game that we are about to start.
