Okay well after an interesting discussion over on What If Modellers, I've come to the conclusion that I'm going to use Hu.174 Signal Red for this one. Now the discussion about colour shouldn't have prevented me from starting, but in the process I looked at a lot of pics taken inside BAS aircraft and I realised that my interior fit probably wasn't a good idea.
An airliner-configured Skyvan has six rows of seats, each consisting of two seats on the left and one on the right, separated by an aisle. At the back, a three-quarter bulkhead has some basic galley equipment on it's back (can't find a good pic of exactly what). What I was going to do was have three double seats at the front, with a personal gear rack next to them in place of the single seats, then the galley bulkhead turned around 180 degrees, then the cargo compartment. However, two things have struck me about this:
1. BAS aircraft carry a LOT of cargo, and significant proportion of it is fuel drums, which are very heavy and have to be loaded with due regard for the aircraft CofG. In my layout, all the cargo would be in the rear half of the cabin, and that might cause CofG and tipping issues.
2. BAS aircraft have detachable seats and they use that facility regularly and flexibly, fitting just enough seats for the number of passengers and leaving the rest of the cabin free for cargo. They don't seem concerned about galley facilities (the Twotters tend to do short-haul anyway) and nor do they seem bothered about separating the passengers from the cargo in the event of a crash. Those two observations remove my rationale for the bulkhead, which would be much more difficult to make QD than the seats.
So instead, I'm going for a more flexible layout: no bulkhead, all the single seats in place and the space next to them free for cargo. That means that cargo can be positioned freely lengthways.

Inside the Dash-7:
Note the lack of separation betwen cargo and passengers (the cargo door is at the front on this aircraft):
