Thanks for the comments. This is a great forum for discussing ideas, and wondering "would this work?". I did mention in my post about cutting down the case and gears to decrease the volume of oil flow. I just used a Chevy in my head because of familiarity, ability to be modified, and low cost. Tell me why I'm wrong in this line of thinking: If a common Chevy pump can provide oiling for 8 cylinders-worth of rotating and reciprocating parts, why can't its volume (and the power required to turn it) be reduced by milling the case and gears to provided lubrication for one cylinder? A Chevy pump is also driven off the cam, so its speed is half that of the crank. I know that there are later model single cylinder engines with pressurized oiling, I'm just not familiar with them.
I guess I didn't say, but was thinking of mounting the pump externally, driven off the crank snout, with lines running to and from the crankcase and canister. I also stated "If you wanted to go really nuts," which I often do when I'm daydreaming or scripting nightmares, forcing oil to the parts could be done instead of just providing a spray. The hollow crank throw on a stock crank filling with oil rather than air could present balance problems to be corrected. There would also be orifice sizes to contend with, to get the right amount of oil in the correct places. Since the whole thing started as a way to get oiling to Dave K2's overhead cam/valve proposition, I guess it fit in the daydream category. I was thinking of a way to force oil to the upper end parts, and to provide cooler oil to the lower end. Like I said, "Might not be necessary, but it would be neat."
