What is better than a hyperdrive for intergalactic travel?

[Maximum7]

I’m trying to write a Star Wars story about someone who figures out a way to travel FTL between galaxies. Hyperspace doesn’t work in the Intergalactic Void, and there is a hyperspace disturbance at the edge of the galaxy blocking travel anyway. I was trying to think of an alternative method of traveling the distance. This drive I envision could ONLY be used in the intergalactic void (so it can’t replace hyperdrive). It allows travel through the void very quickly but NOT instantaneously and there is a weird quantum glitch where the inhabitants of the ship need to wait 2 hours before piercing the veil of another galaxy or weird quantum things could happen to their ship.

Anyway I originally thought of a superfluid vacuum drive but I did a lot of research and it’s unlikely the universe is a superfluid. I know Star Wars science is soft as a marshmallow but I want some fake science that sounds realistic. Can anyone help me? I can’t think of anything.

Wormholes already exist in Star Wars.

A wormhole. Make the trip short using noneuclidean space.

Idea: Time Dilation Inverter (TDI). When enabled, the device swaps the direction of time dilation experienced by the interior and exterior of its field.

Usage: Suppose you want to travel to a galaxy one million light years distant (about 10x the diameter of the Milky Way). Once you exit your starting galaxy, accelerate to 0.9999c with whatever sublight methods are available to you (shouldn't be a problem in a sufficiently crazy sci fi setting like Star Wars). Once up to speed, time dilation will mean the ship's clock will be running 70x slower than a stationary observer, and the length to travel will be contracted to ~1.4% of its original distance. 1 million light years becomes just a paltry 14142 light years, which your ship could cover in about 14142 years of ship's time, but an external observer would see one million years pass.

Now engage the TDI. Thanks to incredible hand-waving plot magic, you see the outer universe slow down to 1/70th of ship's time, but both your velocity and the observed length contraction are unchanged from your frame of reference. You still complete your journey in 14142 years, but the external observer experiences just 202 years! (Of course going faster helps; a TDI certified for operation at .99999c can make the trip in more like 20 years external time, so there may be a storytelling sweet spot in there somewhere.)

But, you say, 14142 years is still a really long time to wait! Very true; that's why TDI units are almost never sold standalone. After you confirm that the TDI is operating nominally, you'll want to hop into a high reliability stasis pod and settle in for an extremely restful intergalactic power-nap. Upon arrival, the ship revives you and you go about your adventure, and by the time you get home, your friends and family will have aged only 4 centuries.

TDI is not competitive with hyperdrive within galaxies because nobody likes waiting, even in stasis.

(I realize this is unlikely to win the sweepstakes, but it was fun to fill in the details once the name occurred to me.)

Canon or Legends?

In one Legends novel, it was theorized the Force could have been used to clear a path through the disturbances, and although that expedition was destroyed by Palpatine and my have also been impeded by some higher force that I don't recall at the moment (within the novel that is), it might have worked, or might work, following the end of "the wars" whether that be in Canon or Legends.

It was actually the Chiss at the request of Palpatine, because if Outbound Flight (the intergalactic spacecraft) had managed to leave the galaxy, it would have alerted the Yuzhaan Vong and lead them to attack while the galaxy was in a weak state militarily.

Checking Wookieepedia, the "higher force" was the celestials (like the family on Mortis). It was theorized by Imperial scientists that they created the disturbances in hyperspace to protect the galaxy from something either entirely foreign or something they had exiled.

EDIT- Didn't realize the meaning of your question.
