Can I join the two halves of a logic board without a test fixture like the Qianli iSocket Motherboard Test Fixture For iPhone X-16 Pro Max, can the two halves be manually jumpered

If you mean you want to power up or test the boards functions without assembling them using the interposer, I'd say no; without a specially-made adapter like the one you're talking about, I don't see how to make enough connections to get the boards working. The two boards are connected via that spacer around the outside edge, and there must be a hundred contact points along the edges of the board, and you'd have to run enough jumper wires between the two boards to enable the functions you want. That means tiny solder spots on each end, and a wire between them. If you take a look at the Qian Li device you're talking about, you'll see there are a lot of spring pins all around the edge; those are the connections you'd have to make.
Frankly, I am skeptical it would be doable, and the consequences of getting even one of those connections wrong could be catastrophic. If you really need to test with the boards separated, I'd strongly suggest getting one of those devices.
Alisha, (@flannelist), do you have any ideas here?

To be honest, I would think that without a jig like the iSocket this would be a very labor intensive ask. Some boards will boards will boot with just the top board (or bottom board depending on which model). But they usually need other components attached to stay on for any length of time.
@elvischukwu Some more detail might help. Is there a reason you're trying to do this?
