Why not ?
Just scan a USAF 1951 resolution target slide and post the scan.

If group 6 element 2 bars are seen then your system is outresolving LF lenses, so enough for LF sheets. If you see Group 7 elements then you have a first class system...
Here you have the result from an X5 (Not a drum, but close, This is scanning 35mm):
You can compare to that.
Other practical tests can be done with an IT8 slide target, for density, etc, Also you can measure stray light.

IMHO numeric tests do not explain all but a lot is explained...
