If it is a stuck ring, using synthetic can free it up.  It is also possible 
to change to an oil with a somewhat higher flash temp and drastically reduce 
oil consumption.

What is the downside to placing the given piston at TDC and using it to keep 
the valves from falling into the cylinder?  How is pressing against the piston 
top of significant difference from pressing against air pressure?

Would it be possible to simply clamp the timing belt to the three sprockets, 
lift out the cam with sprocket attached and reassemble to the original timing, 
negating the need for the cam and pump timing tools and greatly simplifying 
the procedure?
