4 gallon base divided to 4 different 1 gallon meads?

I am thinking of creating a run that will start with 4 gallons, 8lb Orange Blossom honey, yeast, Energizer, and Nutrients ... a basic dry Mead.

Here is where it gets fun. I want to rake it a little early, while the fermentation is active but slowing down, and divide it into 4 meads.

1 dry, 1 gallon as is in a 1 gallon jug to finish out.

1 sweet, adding in 1 to 1.5 lb more honey, and firing up the fermentation, in a 1 gallon to run its course, and a little post sweetening.

In 2 different buckets I will have 1 gallon each of the original but will add Raspberry and Strawberry and about 3/4 lb of honey.
These guys will get raked when fermentation is done, left to settle and raked again.

My thinking is it is easy to start a single large batch, and then rake it down into the 4 individual small meads that are my end goal. Adding the fruit on the later side of the first fermentation I am hoping to achieve a stronger fruit flavoring.

Is this worth the effort, or should I focus on doing each as in independent 1 gallon run?

That leaves me with this, is a 1 gallon run with fruits ok in a 6.5 gallon bucket, or should I look at a different fermenting container?

Thanks,
Bryan

Thanks for the reply ... I found 2 gallon buckets at my local brew supply house.
I am going to go with doing the straight Dry and Sweet mead in 1 gallon jugs, and then fruit will start in 2 gallon, eventually raking off into the 1 gallon jugs.

This will give me individual control.

As for fruit timing, I am going with a late addition so that I get more fruit flavor in the mead. My wife love sweet fruity, and I am trying to deliver that.

This is all new to me, I have read a lot, but I am now diving in (it is the time of year I get to invest in a new hobby)

Thanks for all the feedback, really appreciate it!
