Always ask for ATC help.
ATC will offer a lot of help, sometimes too much. So they would happily accept to keep you within 25 miles from the airfield giving vectors to you ocasionally. You can also request an altitude block so that the levels above and below you are clear, just in case you boost your altitude (elevator failures, etc...). You can almost forget about navigation since you are above MSA within 25 and the controller is separating you from other traffics.
"we have a technical problem, request vectors to remain 25 miles within the airport while we do the troubleshooting" could be a way of requesting that to the ATC.
"we have a technical problem, we are having difficulties to maintain level flight. Request altitude block from 7000 to 5000 ft"
You can alternatively request an extended hold.
With the dual hydraulics you still have FD and A/THR, which makes those scenarios piece of cake, once you understand the nature of the problem and the sequence of the procedure. If you also lose automation... That means the TRE is a baaaad mthrfukr!
