Unless you put the engine together "dry", without any lubrication at all, spinning the engine over to pump oil won't hurt it. Speeds are slower and pressures considerably less at crank speed.
My suggestion: remove the injectors, remove the wire to the "fuel on" solenoid on the IP, and crank it over till you get oil pressure somewhere high on the head. IIRC, there is an oil line on the back of the head. Crack the banjo bolt here and wind it till oil comes out. Tighten the bolt and wind it a bit more, be sure not to overheat the starter. Removing the injectors will of course remove compression and thus strain on the starter.
I've been building high-performance engines for years (motorcycles, atv's, etc) and lube the engine parts with engine oil during assembly. Then I proceed to do pretty much what I just described. I have yet to ever have an engine fail because of this, or score/damage anything from lack of lubrication. I'm sure a diesel is no exception.
