Do you have enough journals for that? Oldham couplers won't support the cam, so you need at least two journals on each side of it, if you're only doing the one cylinder you'll only have the end journal on the one side right?

It's quite possible a mild shrink fit on the sleeve would hold the torsional load, but I wouldn't trust it. Oldham couplers would be nice, if yo ucould buy them off the shelf, (fair bit of work to make) and if you had room to swing them. You dont. The simplest way to form a mechanical drive that'll fit in there is to pin a sleeve radially through the shafts both sides of the joint. I'd use taper pins, nominal dia about 5mm. Pre-assemble the shaft and check run-out and timing before reaming for pins.
All you need to do that is a lathe and a drill press, easy. I've got taper reamers if you decide to go that way. And pins.
Go soothingly on the grease mud, as there lurks the skid demon
Bore through the centre of the camshaft, cut the shaft and put a spigot inside, give it a decent chamfer then bronze the thing back together in correct alignment
H-D did this with the rocker shafts on the original XR750 motors to get the angles right after shortening the 883 cylinders, so it's not like it's never been tried
it's not a bad thing till you throw a KLR into the mix.

Kinky is using a feather. Perverted is using the whole chicken
Im worried about the loading , while its not reversed it is repeated and again while the movement isn't big , the frequency is high and fatigue may be an issue, as well as the interference fit remember it will be running around 100 deg c more or let , which will affect any interference fits
the last idea with the bronze with a sleeve seems the most sturdy , but until you have an idea of the loading .....
Do a free-body diagram , then a loading diagram this will help you making a decision,
just my concerns

What about stainless TIG? When I searched for info on welding gearshafts and stuff for the trike it was the most preferred method I found....
