Sure, all right. Where to start...

For starters, cut out all that stuff about 'heresy' and 'taboo'. Again, if you were doing something the MA didn't approve of, you'd have Enforcers at your neck, and Enforcers do [i]not[/i] fuck around.

As for more usable advice... The integration of magecraft and technology is itself not unusable, just that creating something that we could outright call 'magitech' is not something that should be possible. To that end, I'd recommend re-examining the ways in which the two could be used together and concepts from magecraft integrated into technology (or vice versa). The MA can (and probably still will be) stuck-up and elitist about it, which sorta stays in line with the original concept, but that stuff was going to have to be reworked anyways.
