You're not alone with the splayed hackle wings. Tied to the rear of the hook, it would be similar to a Keys style Tarpon fly. Perhaps a bit over-dressed as such, but similar. Sometimes there is purpose in an over-dressed pattern. It should push a bit more water, and unless heavily weighted, sink at a very slow rate. Both attributes can be desirable sometimes. Such gaudy color could be great for off color, slightly muddy water.
Personally, I prefer matched hackles, usually at least 3 per side. If you lose a hackle from either side it loses some balance. A grizzly as the outer hackle, dyed or natural can add a lot of visual appeal too.
IMO, it would be a good bass fly, even in that color combination. Would certainly work as is for Seatrout & Redfish, Flounder & many other species.
I like it!
