I did a little research and it seems that the new LED rings do not use the H8 bulbs so you cannot duplicate the new look without ring replacement.
I also read that the H8 replacements bulbs by WeissLicht and BMS are not very bright/visible in the daytime.
For H8 replacements most of the E90 folks recommend Lux:

I don't plan to make any changes and will leave the ambers in our 128i.
