The issues you have there is increasing your chance to roll a G rune and auto success by the number of foes you want to attack, and also increasing your chance of a penetrating attack as well (on a successful hit) making the results for multiple attacks and splitting dice pools really odd. Add to that a player rolling multiple times - could well slow the game down.

How? Their 3 attacks would be spread across 3 combat turns; that's not the same, you'd be allowing a PC to attack multiple times within one combat round and because you'd be allowing the d12 to be rolled multiple times you're massively increasing the odds of an auto-success and a penetrating attack within that combat round - facing 3 enemies and you're increasing your chance of a G rune in that round from 1 in 12 to 1 in 4; for 6 attacks that goes up to 1 in 2. I'd take those odds as you're effectively allowing multiple attacks with no real penalty to doing them *and* increasing the chance of an auto success/penetrating attack - that seems like a very broken mechanic.
The way described in my additional rules does have a penalty that you roll less dice in total than you would if you were making those attacks over consecutive rounds. Your way is allowing all attacks in one round with no total success dice penalty. It's a win-win all the way. I personally think there should be a penalty/cost to the total dice you roll when making multiple attacks as making more attacks is harder than making just one.
