I guess if you cant get above the cloud ie. it extends above A100 and you cant get a hemispherical cruising level between LSALT and FZL you just have to plan non standard levels... or just cruise at LSALT if its that tight...
You just have to be careful of freezing rain etc, coz u can still freeze up a couple of thousand feet below FZL, one day i had about 2-3 inches of ice on my wings from only 5 or so mins popping in and out of cloud 4000' below the declared FZL so keep an eye on your OAT too if its close...
