Burst-over finish questions

[u.9]

Using the above-left example (purple-to-clear burst over black korina in satin) with my aim of having a darker, more mystic purple gradient (above-right):

I could go with black burst-over to achieve the darker look, as photoshopped above, but I really want to have trans purple on the back over RSA for a super dark, just-discernable purple tone.

1. If I choose "Transparent Purple (Burst-over)" for the back, will the purple that bursts over make the top purple darker/deeper or just more opaque? (expect the latter)
2. Can I order the purple-clear burst top with trans purple burst-over back (builder options) with an added (custom) black burst?
3. Can I custom order the purple-clear burst top with a trans black (black burst) back with burst-over?

DIY finish is not an option for me at this time, and I want Warmoth quality anyway, not mine
