When I first got my R32, I put in a H3 HID kit. It had a defined cutoff, but lots of glare because of the design of the projectors. Also had two thin columns of light, so it was worse than with halogens in it.
Swapped in FX-R and never looked back. Mini D2S is piss easy to do with the brackets (so would the MLED 2.0 by the sounds of it).
IMO there's no point trying to shoehorn in a crappy LED bulb when you can just replace the whole thing with a far superior unit for not much more money and effort.
