Scarface,

Scarface rappin a slow dope verse, and then comes a Bone member with this lighting speed of lyricism, they could use 2 beats too

Whoever you feel! In my case, I thought Big K.R.I.T. would work perfectly as both producing and featuring. I'll think of more later!

And yeah @miranmakaveli, Scarface would be dope! Since BTNH are fans of him he'd probably make them give their all too.

Yep, someone that can keep the production and the way the album is treated correct! I believe Big K.R.I.T. would do that perfectly. Also they need to interact in the songs and have parts together, to me that's a thing they've done just as great as the singing and fast rapping that they're known for.
The 2 producers you mentioned could give them some heat for sure!

Can't see this happening though. Unfortunately, it's practically impossible to get  Krayzie and Bizzy (I would consider these 2 the creative forces behind Bone music wise) to actually work together at this point. Not saying they don't like eachother, but they are not in same place, musically. From what I know, New Waves was recorded at different locations, with Bizzy and Krayzie not having much imput as far as the hooks etc went. And them not actually being in the studio together is why the songs are so basic. Now, the production was good imo, but they were unable to properly create music together. In an interview, Krayzie talks about how 1st of tha Month came about, and he tells the story of him and Bizzy sitting on the porch one day, coming up with the concept and the lyrics together. That "magic" is not there anymore, sadly. 

The Game

Their tracks with him have been siiick....Full album with him would be amazing

Each other.
