I have done that for the attachments that need the Q/A auxiliary hydraulics. A blue zip tie on one side. For others with fewer powered attachments, that might pencil out. Given the number of powered attachments that I have, the 4-way adapter route is cheaper for me. If I was going to switch it flat face couplers, I would certainly think of doing what you suggest.You could also put females on the PTO out, and males on all the implement hoses, and color code them for normal operation. Then swap if you need to reverse.
Not nearly as elegant as the flip of a switch or lever, but I'd guess a whole heck of a lot less expensive.
All the best,
Peter
