It is not...it's merely a financial hurdle that some day I hope I'm in a position to bring it back to retail.

Yes. That would work just fine.
I've used a very similar mix - although not quite as complex for outdoors in the midwest.
When growing outdoors though, I really tend to favor mixing in SOME local soil...the local fauna is going to help you in the end.
Don't think about organic soil as a set volume of medium and then making the mix stronger or weaker by adding to it or taking away from it. Instead, think about it how big the plant is going to be and adjusting the volume of the soil accordingly. So bigger plants or longer flowering plants don't need a "stronger mix" - they just need a larger volume of soil..
If you are planting in beds or containers then the above works fine...if you are planting directly into the ground, you may want to consider this post:

At 42 - pretty much want to keep it to anything that finishes in 10wks or less. Make sure you are getting early morning sun as opposed to late evening sun if you have to pick one or the other. The main reason being, the early sun helps dry the dew off the plants and keeps them from developing mold or budrot.
The following were in peat, local soil, county compost, EWC, perlite and an even simpler amendment recipe that is not as good as what is listed in the first link:
This was planted middle of may - pictures were mid July - I never did get harvest pics that year. This was much more of a guerrilla grow - and was only looked in on once a month...so really not the best example...but you can see the plants are healthy at least.

Just to give you a rough idea. If it was a truly tended garden...your results would be far superior.
