I've put used solid lifters from a different cam (which had wiped a lobe) on another hydraulic cam which was also a used one.
I picked out the lifters with no visible dish.
The lifters were incomplete so I used a 3 more solid lifters from another used stash.

I put some cam-paste on them and ran them through the rpms for about 5 orso minutes.

Ran it for three years without issues.
This was in a 496" stroker with Edelbrock heads.
