Maybe I'm missing a point here but, lifter oiling is almost always just oil being slung off the crank and what drains back from the valvetrain area. My GMC has flat tappets with 100# on the seat and 300# open and shows no sign of wear and never needs valve adjustment. I'm also lifting the valve more than 0.600".
I made sure the oil has lots of ZDDP to combat wear associated with flat tappets.
I don't think you need to reinvent the wheel without seeing a significant gain in performance or reliability.
