I was trying to create a speedsolving method based on DR/Belt, and here are some of my ideas:
DR:
I think the fastest(not necessarily most efficient) way to achieve DR is EOBelt -> CO. Belt edges don't have to be solved, they just have to be in the E slice and oriented. After EOBelt, you can use TSLE Edge in slot algorithms to solve CO of one side, and then solve CO of the other side with OCLL. Alternatively, to avoid a z2 rotation, you can orient 3 corners on the bottom during EOBelt then orient the remaining corners. You could also blockbuild DR F2L and do OLL, but I haven't tested this too much and I don't think it would be too efficient.
Solve after DR:
I have thought of 3 ways to solve after DR that could be fast:
I think if you do
EOBelt -1 edge + 3CO
TSLE
Reduction to <R2, L2, U2, D2, F2, B2>
Roux finish
it might me a decent method.

I have thought of 3 ways to solve after DR that could be fast:
- Reduce to <R2, L2, U2, D2, F2, B2> then solve F2B, which leaves you with 4c
- Blockbuild F2L then PLL/ Blockbuild to F2L-1 Corner then TTLL
- Blockbuild 223 and finish with Mehta
