Why not try dslrController, an Android app which does nearly all that you mention for the Kuuvik Capture? Of course, the price is about $10 for dslrController and it workswith a tablet or phone, making it much more practical in the field. In my case I mount the tablet to my tripod leg with a RAM bracket. Another option is wireless control using a TP-LINK TL-MR3040 3G/4G Wireless N150 Portable Router, Battery Powered, AP/WISP/Router Mode, Compatible with Selected ATT/Verizon/Sprint/T-Mobile USB. This rig is not perfect, just very good. It provides zebras, peaking, full remote of all camera functions, focus stacking, HDR capture, and combined FS and HDR capture. YMMV.
