There is no way to reverse a compaction.
You can initiate a user compaction on a single file though, see nodetool (i
think) or the JMX interface.

The issue with major / manual compaction is that it creates a one file. One big
old file.
That one file will not be compacted unless there are (min_compaction_threshold
-1) other files of a similar size. So thombstones and overwrites in that file
may not be purged for a long time.
If you go
When the default compaction strategy the SSTables are grouped into buckets,
where the size of every sstable int he bucket is within 50% of the average size
of files in the bucket. There is also a catch all first bucket for all files
less than 50MB (by default).
The min_compaction_threshold CF
