Well if you haven’t already, I would recommend you play it with ICRPG rules as written (despite your lust for fistfulls of dice). Although you d6 design notes are intriguing.
You would be surprised at how much you are not missing. It is flavorful, fast, and most of all it feels like Shadowrun should have been played… there are a few mechanics that I would like to see added that I just haven’t gotten to do, yet. But all in all, I like playing it with ICRPG.
There is also a Dungeon World version of Shadowrun called SIXTH WORLD that was quite impressive in it brevity and speed of play, but once I tried ICRPG Shadowrun… it was a no brainer … Game On!
P.S. I am not advocating that your system/method is bad. A lot of experience with both systems has shown me how ICRPG opened up the world of Shadowrun (and many other games) to greater storytelling. Less drudging thru long combats. The rules got out of the way and let me play like a kid again. Honestly, I would love to see @Runehammer run a game of Shadowrun using his rules and style. Just sayin’
