Straight from Camera to Adobe Camera Raw

[Plancton06]

I have tried multiple workflows, Phocus and then export to tiff and finish in PS, Phocus + Lightroom (better perspective correction) and also Phocus in IPAD + Lightroom.
I miss the simplicity of my previous workflow before the X2d, simply opening the camera in storage more and drawing files into photoshop, which would automatically open them in adobe camera raw, then do basic developing there and click open to finish and save from photoshop. The end result is that the raw files remain in camera, and the final file is produced in photoshop.

I know it has been discussed, but will I miss color information if I set the camera raw preset to import the 3FR files as Adobe Prophoto RGB?

What are the possible disadvantages or issues with this simplified workflow?
