First off, all your thought processes do make sense to me there so that's great. I took a crack at this and had dropped it over in the other thread, so let me copy all that here. The rack I built out is half as big as the one you put together, and has a lot of the starter modules that will help you learn so that something like the SSF Tool-box isn't so intimidating. From where you're starting I think aiming for 104HP in 3U is a good step, and will let you develop your understanding and comfort without spending too much cash up front. Anyway, see below.

@Nabroc I had a minute so I took your original rack as a starting point and made some adjustments:

Notes:
1) I don't believe the Mantis has a 1U row, so I removed that, but much of what you had there I replaced in other utilities.
2) The Ginko looks like a sick module, but I'm wondering if you have to code with it? Either way I might nab one.
3) I replaced the Erica Synths clock module with a PNW (which is really fantastic).
4) Kept the Ladik LFO, it looks sweet.
5) I added a micro Rings since you mentioned wanting plucks and strings and it's a really great Euro module.
6) Swapped in a Maths plus an Intellijel Quad VCA, Maths is great, can do EG and LFOs for you as well as attenuation/attenuversion.
7) Added an FX Aid since FX in the rack go a long way.
8) Added in a Happy Nerding Stereo Mixer as it's reasonable priced, three channels should be good, and it also has a headphone out so you won't need another module.
9) A contender that didn't make it into the rack above is the 4MS Ensemble Oscillator. If you're interested I can make a version with that guy in there, but tons of experimental range and can sound sweet and sugary too.

This comes in a good bit more expensive than what you'd posted, and I'm definitely using a few popular modules here, but I think it'd be a good starting point for exploration and that empty row at the bottom will give you lots of room to expand as you learn.
