I borrowed 2 diving tanks from a friend.  One is a 12L, the other a 10L and tried various configurations of how they might fit.  I have now ordered my own.

 

I worked out how much air I need for main tank blows and made a spreadsheet that can easily tell me how much air I have at different depths and how many times I can fully blow the main tanks.

 

Bearing in mind that hopefully I wont need to blow mains at depth and can just come up on variable, blowing mains at the surface.

 

Calculated volume of main tanks. (Estimated using tubes, which is on the safe side as the actual tank shape is less, but difficult to calculate).

 

Main tank volume (fore and aft) = 86L

 

Scuba Tank Volume(L) x Scuba Tank Pressure(bar) \ Diving Pressure(bar) = available air in liters at that depth.

 

That answer divided by the main tank volume gives amount of full tank blows.

As I can get almost 2.5 full tank blows at full diving depth with a 10L 232 bar tank, I am going to use 2 of those.  They fit better.
