How about the guy(s) from MWA Nova in Berlin?
It's patented laser-based perf detection and image stabilization system can help here. The lasers replace sprockets, so there's no issue with jumping the sprocket teeth.
The laser system compensates for shrinkage on a sprocket hole-by-sprocket hole basis to keep the image vertically stable. That makes for a faster turnaround and less post-transfer work and storage needed.

The new MWA flashtransfer Choice 2K+ is one of them. The sensor is 2.3K x 1.7K, for a 4:3 aspect ratio that matches most material likely to be transferred.
The combination of laser-based positioning and gently curved gate(s) on the the Choice 2K+ will help keep the film flat at the point of imaging and better aligned, especially with the wavy and curly "lasagna film" John described.
By way of information, the Choice 2K+ can do 8mm, Super8 with magnetic sound on main and balance stripes and 16mm with mag stripe and optical sound, along with silent 9.5mm, 17.5 "split 35" and 28mm.

There could be benefits from scanning on the Golden Eye III and its software as well, depending on the end result needed. It has 2K and 4K sensor systems available, as well as optional gates so it can cover 8, 16, 35 and 70mm film.
If further stabilization or restoration is needed, various products could complete the work. Andreas mentioned Blackmagic's DaVinci Revival, repped by my friend Gary Adams.
The Phoenix line of restoration tools from Image Systems (maker of the Golden Eye III) is another possibility.
Most software developers are providing short-term trial versions for download, so it's fairly easy to see what might work on a particular piece of film. Check respective websites.
Hope this is helpful.
