when you say straight up, do you mean pulling it with the engine upside down, or pulling it with the engine sitting on the rear main seal.
either way, i don't see either as being too good an idea if you intend to use the crank, unless it takes very little force. and chances are, you're going to have to grip it from a rod journal. maybe not the best idea. if you pull it with the engine on sitting on the rear seal, well... you have the main cap thrust areas that will not let the crank move more than half a millimeter anyways, so i dont know what that would achieve.
also. what you probably COULD do, is loosen all the bolts on the oil pump, and give it a tap from the back side, so that it pushes the crank sprocket forward a bit., then when you seat it back in the position it is when bolted in, you should have screwdriver clearance.
