I've wondered if there is any use for various .22 brass in Scale (short, long, long rifle, mag). Seems as if they could be used as a spent mortar round or other. |

Might, the tricky part is the rim, which is not rebated the way "cased" ammunition for artillery often is. That rim is 6.8mm, at 1:35 that's 238mm in scale, around 9-1/3". The "hole" in the end is pretty big in scale, too, 5.68mm scaling up to 199mm, about 7-7/8". Most arty stops using a case around 155mm/6" bore size just for the sake of the redlegs who'd have to tote the charges around.
Since I looked it up, here's the case lengths: .22cap is 7.2mm or 252mm; .22short is 10.7mm or 267mm; .22long & .22LR are 15mm or 525mm (20 5/8"); .22WMR is 24mm or 840mm, that's 33" in scale. That's 1:35; other scales will differ.
Tiny nitpick: Mortars do not have a "spent" case. The "case," such as it is, is in the tail of the mortar "bomb." It's surprisingly similar to a shotgun shell. It rides along with the bomb out the end of the tube. Mortar rounds (usually) have additional charges draped or wrapped around the tail boom. These can be stripped off in increments to decrease the range the round fires as required. Modern military mortar is the most complicated simple thing to lug around at times. (Though the ornate early WWII german 50&60mm are near-ultimate in "gussied up".)
