Blade SSD Repair in Fusion Drive and data recovery from HD

I have a problem on my old Late 2013 iMac with 1TB Fusion drive (128gb PCIe x2 Blade SSD + 1TB HD) where the HD is recognize but the SSD is not showing up and because it's a Fusion drive setup the computer won't boot (Just shows ? at boot). I am trying to figure out what my option are for getting the machine back running again. First, I have a Time Machine back but only for up to Oct, 2025 after which the TM drive hot disconnected and never reconnected. So is there a way to recover the missing 2 months of data from the HD drive without the working SSD (serving as a cache drive)? I have a 128GB PCIe x2 SSD from a old 2013 MacBook Air I upgraded that is not being used. Can I use this to somehow restore the Fusion Drive setup and get my missing 2 months of data back? Are there other option for data recovery on the HD? I was able to remove the HD and run Spinrite 6.1 on the drive via a PC and it found no errors with the HD. I can't of course run the SSD without a Mac specific external SSD enclosure due to Apple using a proprietary SSD interface on it's Macs. I going to try and create a bootable external drive with some version of MacOS to see if it detects a internal SSD at all. I should point out that the iMac was running Open Core Legacy Patcher Software on it so I could run a more recent macOS on it then officially supported by Apple (macOS Sonoma) if that makes any difference.
