I've done it before on a quiet system and it worked fine. Still think
its a bit risky if you cant get to it for 2 days.

If you "urgently need to install new software", then a small possibility
of breaking the system for 2 days is probably a show stopper. I'd
continue with your approach (as a temporary solution) of migrating bits
of /var to a different LVM. If moving /var/logs didn't help, you need
to track down the big directories. Try
du -sh /var/*
then drill down though your big candidates
/var/cache/yum, /var/spool, and /var/tmp are always candidates for clean up.
Hope this helps.
