What about an electric remote pump?

Yup and a lot less compression when there's no fuel mixture firing off pressing against the pistons/bearings. I've taken engines apart and there was still oil on the bearings and cylinder walls. To each his own.

These have a shut off valve that holds the pressure. It literally is a manual ball valve. Same thing they use on farms for irrigation lines or even your water faucet. These tanks hold something like 3 quarts of oil and when you open the valve, it pre-lubes the engine. Then you start the engine and it uses the oil pressure to refill it, and before you shut the car off, close the valve if you plan on letting it set for a while before driving it again. It its only going to set for a couple days, leave it open. There not that big overall, but I could see in something like an early A-body maybe a bit tight.

Just start it.

Exactly. I've taken engines apart from farm trucks, motorhomes, etc. They sit for years sometimes before starting. Owners will just crank until it starts. The bearings will look fine. Some oil will be retained on all the bearings. Crank it until it gets fuel to the carb, by then you should have primed the oil system.
I've just cranked my 383 Challenger over until it starts for 20 years and it still runs fine. It sits for 6 to 8 months a year.

Just cranking an engine that has sat for long time....is enough to for the engine to get oil pressure....the oil light in my cars goes out almost immediately. The ones w gauges show pressure just as fast.

My Imperial, my Super Bee, my Ram 350; I've owned them all for 20+ years. All sit for months (3, 6, 12, 24) without being started, and I do nothing other than start them and go. The longest each of them had sat without being started has been 5+ years. Start and go. They are all stock engines, ranging from 70,000 miles to 150,000 original engines with no rebuilds. I just drove the Super Bee on a 7-hour road trip to Hodge Restorations and back. I use the truck every 8-months to go haul something or move something to or from storage. The Imperial gets driven once a month or every two months for an hour or two at a time. Start and go. Just sharing what I know! Cheers.
