Forget it. Here's what I'd do.

I assume you have fresh oil in the engine. Crank the engine briefly with the filter off. It should prime and pump oil out the filter mount in about 2 seconds or less. Even if it has to crank 5 or a bit more, that won't hurt a thing. Fill the filter and install it

Now pull the oil sender and figure out a way to pump oil into the engine. Grease gun is slow but will work, I'd rig some sort of pressure vessel. And refrigeration can. Section of pipe or even PVC Something that will hold about a quart, that you can pressurise and force oil in

But I doubt I'd even do that. After priming the pump with the filter demounted, I'd just fill the filter and crank it. Leaving the pluts out will ease that, but if it's near "ready to run" wire it up and run it. Squirt a bit of oil in the plug holes to lube the cylinders and rings.
