Have you considered the heated redstone generators? 320RF/tick each, and don't need a ton of redstone. Although, it'll be more than you'll get sifting, so you'll want to have one or two Bloodwood trees on auto planting/harvesting. You can feed the logs through a cyclic assembler or two, then into a condenser if you're wanting a singularity for quantum bridges. Or just send them as-is into steam dynamos. Unfortunately, being fireproof, you can't smelt them to turn them into charcoal, but you've got plenty already.
Excess saplings can be fed into barrels for dirt production.
You'll want a dedicated magma crucible for the gennys, but that's a small investment.
