I wish

I'm still trying to find captain crunch
This could point you in the right direction:

That was my first attempt at DIY (such as it was) and within a month I'd stopped buying off the shelf completely. It really did taste
exactly like the cereal. FSUSA started selling a version a month or so after that post

.
Knowing what I know now about DIY, I'd say flavors along these lines to make it from scratch:
Honey (the primary note in Max/Boro from FA)
Brown Sugar and/or EM (for extra sweetness and body)
Peanut (to replicate the 555 "graininess" - could also use DK-Tab from TPA)
Blueberry
