and where can we get these said pegs?
This particular setup I actually carried over from my Blackbird.
The footpegs themselves are from Oberon (based in England). They are black-anodized (which will eventually wear away after a lot of hard use, as you can see at the outer tip). The grip studs are actually stainless-steel socket-head bolts. I've had these pegs for several years.
Nowadays, Oberon makes 3 different types of footpegs: "studded", "racing" and "touring", the latter being a touch wider and longer for added comfort:

With regard to the Footpeg Lowering brackets, these are custom made by a buddy of mine on the Blackbird forum. While these CBR1100XX lowering brackets do attach to the K8 footpeg hangar bracket just fine, you can not retain the stock K8 footpegs. They are wider than the stock CBR1100XX pegs, and thus these Lowering brackets need modification. I have sent my buddy my OEM footpegs off my K8, and he is going to fabricate a set for prototype testing. I will put them through the wringer when he is done, and if they are good to go, he will fabricate them for production if there is sufficient interest.
Mind you, they will not be pocket-change.... likely enough, these will be a touch more expensive than the Buell mod. OTOH, you get to use any after-market footpeg you want (Oberon or otherwise), and the kit is "complete", with new stainless steel clevis pins, washers and cotter pins:
