Thanks Guys, you've just confirmed what I thought.

I know I'll prefer the look of the Coffin type ones on the M1000, so will probably swap them over winter.

The spare Front brake reservoir is the original off my M900 which needs a rebuild kit, so will be a correct twin disk size one.

I lived with the reduced capacity of them when used with Clip-ons on my M900, so am aware of what I'm letting myself in for.
I found that if I put the bike on an 'Under-Headstock' type paddock stand and turn the bars to full lock the coffin reservoirs were perfectly level for bleeding purposes.

I've even kept the CCW spacer kit I had on the M900 if I get any issues fitting them on the ST type clip-ons I've used.

Of course the remote type ones look right on my 1000SS/SL so will be staying.
