I’d think so, if you can see that there are 4 strengthen lengths of folded-welded sill, then why not try to fabricate bespoke adaptors to place on your trolley jack saddle maybe 150mm long, shaped to sit on either side of the strengthen area using the folded section only as a “locator” and fitting high density rubber on the contact surfaces.
In an ideal world you might need 4 different profiles to exactly suit each of the 4 positions.
Or, if that sounds like being too much bother, just buy a suitable slotted compliant adaptor and like others live with lifting on the folded-welded points.
