A couple of ....(not sure suggestions is the correct term):
1) post in the general topics area under hydraulics—it seems most of the hydraulic guru’s hang there
2) as you search for info, this is commonly referred to as T-N-T or some variation of that
3) consider looking into how a loader has had hydraulics plumbed for similar tractors. As I understand what you want to do and the 2 valve functions of a loader are not that different. A loader has a frame lift/lower hydraulic function and a bucket curl/dump hydraulic function. Substitute tilt and top for lift and curl and then the difference is largely where you are running your hoses to.
On my Ym2002D, somewhere along the line before me, the pressure line from the pump to the 3PH was cut, fitting and hoses installed on both sides of the cut. Pump side goes to input port of valve and the other goes to the tank port on the valve. Quick connects were used for the potential removal of the loader.
I am far from a hydraulics expert, but I do not know why such a process would not work for a 2 spool valve for rear remotes or direct plumbing to your 2cylinders for TNT.
I do not personally like how mine was done for hydraulic supply, but it works.
