I'm always willing to lend a hand. Long story short...you can lower it if you do it right and it won't mess up the handling. Is it the ideal track/race setup? No, not without a lot of other work. But you've been realistic and said you have no plans to track it so don't worry about it. Do it if it makes you more comfortable on the bike, as that is what is really important. If I were closer I'd come over and help you do it for that matter, but Cbus is a bit far. Nothing too difficult about the job itself but you'll need to figure out some way to lift the bike by the frame and take all the weight off the rear tire/swingarm. The front forks can be raised with the help of a buddy on the other handlebar. Loosen the bolts on the clamps, lower to desired height, and tighten.
