Yep, T-ripper is good to process 1000 mosaic tiles done with 16803.

End-game for me is a 155/7, so this is good to know!

That's why the silicon gods granted us ThreadRipper! TRs help immensely even with the 60mp images of the IMX455 cameras. I'm waiting semi-patiently for AMD to sort out the supply of the new generation of ThreadRipper so I can return to doing things like local normalization and even 2x drizzling in PI and not have to wait half a lifetime for those processes to complete.
