Alright, I'll take back what I said before (it was very late).

I still don't see how these reactions deal with fusion *specifically*, pressure is easily manipulated with PUMP and such in many saves, so extreme low/high pressure is used a lot, which can risk a random old save getting a new reaction it doesn't want.

That's not to say new reactions wouldn't be neat and useful, and your chain of reactions sounds nice, but I'm not sure how often they might occur naturally outside of a factory (if at all).  Compatibility with old saves can always be adjusted for (or sometimes ignored...).  I think the best way to test these would be in a mod (even lua could do this).
