However, she has decided that NOW is a good time to learn her colors, numbers, and letters. So she knows those now. We haven't worked with her, she's just picked it up, lucky 4th child

So, how does it sound that now while she's excited about learning these things I slowly work with her over the next year on LHTH as written, then go through it again, but don't do the "fine motor skill" work and sub the right side of LHFHG? Like go through the Bible stories and Count On Me pages and the letter work, etc between now and when she's 4. Then when we get done with that, do the Bible stories again, but do the K level FMS books instead of the other things.
Then when we get to LHFHG we'd do 1st FMS, K math, and storytime with LHFHG?
Do you think that would work? I know with Julianna we did LHTH with additional FMS books, and now K level LHFHG half speed. I'd probably do LHTH half speed with E for a while, just give her something to do while she really wants to know colors/letters/shapes/numbers etc.
Like I said, I KNOW I'm overthinking it, and probably in another two weeks she'll move on to something else...
