Yes, that makes plenty of sense. However, all that regex processing *could* be a bit of a fruitless drain so, if you can, cache the page content (using CF and compressed using the method you describe). Caching the output could really speed things up but, of course, can be a problem if there's session/logged-in user based output. Testing should be the decider on how much the white space processing effects things if you can't cache your output.
There's a udf on cflib.org to do with html whitespace stripping: http://www.cflib.org/index.cfm?event=page.udfbyid&udfid=812 Another thing to look out for when using the 'extreme', single line compression is that it can break some inline javascript that is missing optional semi-colons.
