Andy,
That sounds like quite a good way to approach it.
I don't want to string it out over too long a period, but it does sound as if it's possible to have too much of a good thing early on in the course, so yours sounds like a good compromise.
Perhaps on our next visit to Le Touquet in the haze we can pick up their ILS just off Hastings, call final at 30 miles and blast on in like some others seemed to be doing the last time we went there!
