Update, after a few more months, 3.5 months in total now. I'm still with it, although I modified things a bit. The L-O switch was giving me problems, so I took it out for a couple reasons:
1) looking at the key-frequency list, it isn't a huge difference, like N-J is.
2) looking at my fingers on the board, my right-hand ring finger is curled down and just hitting the top of the L as it is, and it's basically no trouble to go up to the O.
Given those considerations, and the premise that we're trying to make as few changes as possible, to preserve Qwerty-compatibility, I modified the set up files to add a minimak-6 option (not the same as the other minimak-6, which is apparently a 1/2 way point to minimak-12, and flips the F-R keys instead... this is my final step, and I really wanted the N-J swap, so I called my version "Minimak-6 JN").
Sidebar: Initially I thought there was only Qwerty and Dvorak and those were the only two options that existed. Then I ran into Colemak, and further research led to Minimak and others, and after installing it, I saw how you can change any key you want on both PC and Mac, so that gave me the freedom to go out on my own keyboard specialization. I might be the only one ever using this particular layout, but that's okay. I'll set it up on my computers and it'll work for me. I expect future operating systems will always allow these changes, if not making them even easier to do.
So after the brief flirtation with Minimak-8, I'm now comfortable using Minimak-6 JN. Initially my QWERTY rate was 65-70 wpm. I'm not using QWERTY much anymore, so it takes a good day of adoption to get back into it, but I can still hit 60-65 once I do that, otherwise I'm in low 50's. My Minimak time is generally 50-55. I figure it took me decades to get to that QWERTY level, so I'm not worried that Minimak is still slower. Even though I'm at a computer all day, I sit and think, or read, more than I type, so 50 wpm does not hamper my job at all. Meanwhile it just feels more comfortable, and it was fairly easy to set up all the computers that I use, so I intend to keep with it full-time. Even though I can still go faster on Qwerty, it just doesn't feel as good anymore. I use the PKL program at work - easy to put it back to normal mode if somebody else needs to do something on my computer. At home with the Macs there's the flag icon on the menu bar, so that's easy to change too. I haven't tried to change the iPad, I don't think that's possible, but that doesn't have touch typing anyway. It hasn't bothered me.
