I think you'd want a banjo with a compression type fitting like you see on brake hose's just in case, not sure how long your engine would last if one of the hose ends came off or how long you would stay on if your hose managed to coat your front tyre in engine oil.
The engineer helping me with my bike has said he will have a look at fitting a braided hose although he hasn't actually pulled the old one off yet to see if off the shelf items will do the job.
Will be taking the engine to him for some helicoils in the new year so will ask him to look into it then
