I am intrigued by the concept, but I don't think there are enough space in 94X to have flipper knob.
Take a look at from spine into the space at where sub frame jimping. The "flipper lever" need to be behind the blade and clear AXIS lock, making it to have measly 1/8 inch and it extends from blade line to have sufficient protrusion on spine. AS you can see in 300 flipper, handle needs to be re-designed as well.
I think BKC can make 300 into narrow and longer flipper.
