Sounds like a lot of work to me, but if you are convinced you can teach them sufficiently well so they don't lack any knowledge/skills they will be expected to have in secondary school, go for it.

In other words, don't let your own ideals be the cause of your kids ending up in a situation where they will suffer academically. You may feel good about teaching them the stuff that you think matters, but if that means they have less chances in life, you've only done yourself a favour, not your kids.
