Work around for the 3.5GB Limit? Food for thought!

It seems we (Win7 users) will have to cope with the 3.5GB limit for a while longer as changing it is in the long term planning.
I'm thinking about a workaround as I want the whole track in my video.
The rest of the gauges don't bother me (yet) as I don't need them.
If you want them you have to test it for yourself.
I think you need to set the maximum speed of the speedometer by hand (we did that trick some time ago on this forum).

I am recording in 1080p 30fps, if you record differently you'll need to adapt if possible.

So I want the whole track in my video.
I've already exported 4h of a violet screen with only a track, that worked OK, the chroma thing didn't worked out that well, so I won't try that again.
To have the whole track I need to have a video as long as my track, in my case four and a half hour.
As the 3.5GB limit only permits pieces of normal 1080p video of 24min it won't work.

When I have just a Blue 1080p screen and export it the size is relatively small, about 7.6MB for 10 min.
With only a track added, my 10min video becomes big again, 165MB.
When I speed it up 8x it becomes smaller, 20.5MB. (1 original min => 2.6MB)

What If I could have a piece of my video at normal speed plus a piece of Blue speeded up 8x?
That the GPS data would be out of sync on the Blue part wouldn't bother me as I will cut it off later.
Later on I could edit the video's, putting them together and cutting off the Blue parts in another video editer (PowerDirectorPro).

I have done some calculations (rounded numbers).
I need to have 4h 30min of video.
If I have a Blue+Track of 4:30h at 8x it will be 700MB
Normal 1080p video needs 3.5GB/24min = 150MB per minute
The track at 8x needs 2.6MB per minute.
So 1080p video needs 148MB per minute more space.
Maximum video size is 3500MB.
I already have the track, 700MB, so there is 2800MB left for the 1080p video.
This would mean 2800/148 = 19min of 1080p video.
To add all up I could have 19min of 1080p and 4h 11min of track at 8x.
This would mean trimming the Blue and adjusting the track.
What if I didn't bother to trim and adjust the Blue part and let it be 4:30h with the whole track?
The track would lie over my video track, but as they are the same it wouldn't show.
What would it mean for the minutes of 1080p I can have?
It would be 2800/150 = 18.5min, so only 30 seconds less.
These 30 seconds probably will disappear somewhere in the rounding of the numbers.
For me it means 4:30h / 18.5min = 14.6 => 15 parts.
These 15parts will have 18 min of 1080p video and 4:30h of Blue with Track.

At this moment I'am testing my theory.

Any comments?
Could this work?
Am I going wrong somewhere?

    Result of the first test:
    My video: 12min 19sec normal 1080p video + 3hour 46min 59sec violet (didn't bother to make a 3h blue video, just take one colour).
    The normal video part at 1x speed, the violet part at 8x speed.
    The whole video has the Track overlay.
    Total size calculated 2.189GB, after rendering it came out to be 1.989GB, that's better than calculated.
    When I started the export, as expected, the message popped up about the 3.5G limit, but I ignored it.

    My current calculation:
    Total time of the track in minutes = T
    Blue screen with track is 2.56 MB/minute = B
    Size of 1080p video at normal speed is 149.83 MB/minute = N
    Maximum size of the video is 3586MB = E
    Maximum clip duration for the 1080p part = R
    (E - (T x B) ) / N = R
    I will try to clip off the violet/blue part and upload the result later on.

    Next test will be "what will I win when turning the overlay OFF on the violet part"

    Now I've done another video.
    21min 32sec of normal 1080p with time and track + 4h 29min 1sec of violet with the overlay turned off.
    This resulted in a video of 3,462,100kB
