Installing languages post 1803 using LXP

We are still using SCCM, in this case 1910 to deploy Windows 10.  Largely because well, Intune sucks, and Auto Pilot doesn't come close to being able to deliver our requirements.

We have a requirement to install up to two languages for a user as part of the OSD task sequence. The base OS is US English. Our requirements also insist that everything be installed prior to the user touching it (just one of the many reasons we can't use Auto Pilot).  The one that's causing us fits as we try to upgrade our standard OSD to 1909 is that we can't get languages to load.  Yes, I know we need the 1903 LXP files, there aren't any for 1909.  Yep, I know that we have to use the LXP (Local Experience Packs) now.  I have downloaded them from the VL site, and even better used the S4B to add a language to the store (Offline) and then from there create an SCCM app.  Easy, or so I thought.

Well, here's the challenge, I get a dependency missing error, both with the S4B appx, and when I try to install it using PowerShell Add-AppxPackage.  The error I finally tracked down for both of them is missing dependency. If I install the LXP from the Microsoft Store and do a Get-AppxPackage I get, no listed dependency.

So my question, has anyone figured out how to get an LPX installed as part of an OSD task sequence?
