Aaaah they're actuals. Well using those figures, your airspace volume ratio would be about 1.4:1. I assume that's without the springs in.
Thinking about the seal issue, fork seals are usually of the lip type (like a bearing oil seal), so when you increase the pressure inside, the lip presses on the shaft (fork leg) harder. It may not blow out, but what it will do is wear much faster. So, initially it may hold, but then it will probably start to leak a bit, and because there's so little volume inside the fork leg (not like a car tyre), the pressure will leak out really fast, any you'll have to top it up a lot. I've done a bit of work with air suspension, and I found that you really need something that's designed to do it from scratch. Otherwise the seals and the internal dimensions are not right.
