I'm a bit confused with what part of the workflow you'd like to eliminate. If you are accustomed to using Adobe Bridge and opening from Bridge into ACR, no need to first convert to DNG format. Bridge will open an RAF file directly in ACR. Thus, no need to convert RAF to DNG if you don't want to.
I've been around and around on the merits of DNG. My conclusion is it's a mostly a solution looking for a problem. As long as Adobe and other RAW file apps keep supporting proprietary file formats like NEF, RAF, etc. I just don't get the point of DNG. Also, other RAW convertors often punt when it comes to handling DNG, e.g, they may open a DNG made from a NEF file, but not from RAF, and even using a linear DNG conversion is no guarantee that other RAW convertors will know how to handle the DNG format correctly. Seen many DNG fails before with non Adobe software. DNG is just not the universal open source RAW format solution that its creators had hoped would occur. I don't want to go there again.
I also much prefer the Bridge/ACR raw workflow to the LR raw workflow, but that's a personal choice. Both use the same Adobe RAW file conversion engine.
