Personally I don't find the idea of changing the power plant fuel intrinsically or otherwise bad.
OK, but that's not what I got from your original statement.
Just a change, with repercussions, so it needs work to implement.
What work? That's what I've been trying to point out, that it wouldn't involve much work. Granted, the deckplans would all be wrong, but they're all buggered up anyway (There's not a single design I know of that actually spends 40 squares on the bridge). As for basic stats, how much work does it take to change
"A Free Trader. 200 tons. Jump-1, 1-G. 30 tons fuel. Model/1. 10 staterooms, 20 low. 2 hardpoints. 82 tons cargo. Streamlined. 4 crew. MCr37.08; 11 months."

?
And it's low on my list of "fixes" as well since it works for me as is.
It's only just dawned on me in the course of this discussion that PP fuel tankage for BT differs from PP fuel tankage for HG. That where HG requires 2 tons of fuel for a Free Trader (already ridiculous), BT actually requires
TEN tons!
So I have to say that much as HG PP fuel tankage doesn't work for me, that goes double (or rather, quintuple) for BT! ;-)
