If you wish speed as the strategic alternative there is only one choice and that is the Mossie. IMO that selection points toward single or two ship formations to limit the intercept tracking and stretch German defenses. Single large formations, having no defensive firepower, seems foolish and in any case the loss rate will still be high. More effective? I don't see why the Mossie ability to deliver a bomb load better than a Halifax - on target - is improved unless the Mossie drops to the deck and makes its bomb run from there. In addition, Low altitude tactics influence fuel storage vs bomb load vs range calculations.
Low altitude bombing does improve accuracy, but for the Mosquito it did have a couple of other benefits.
One, the German radar would not pick the intruders up as quickly, if at all.
Two, the Mosquito's performance at low level compared very well with the German fighters - Bf 109 and Fw 190.
Three, the Mosquito's great blind spot to the rear and below was not exposed.
The third is also applicable to the Lancaster and Halifax, as their defences did not cover beneath very well.
The downside was, of course, range is lessened.
