Nice battle report. I think the problem you are ging to hit is that basically gamers are lazy. Having a rule set to cover every period, if it works, seems to be ideal but when it comes down to it very few gamers will bother. Why? Because they want every force list set out for them.
This happens to all rules that spread a large period of time, people moan because the 'lists' aren't there, even if it is possible to work them out.
I talk from experience here, Flying Lead covers the whole shooty period and there is an online character builder but still people will not use it for such and such because the 'list' isn't there.
Anyway good luck with them, if you do a PDF I reckon a lot more people would pick them up.
