Vanilla Butter Bastard, sounds amazing but wondering if can condense?

I love vanilla but have yet to mix my first recipe. I came across this recipe while looking for a buttercream frosting type and was just wondering if all 6 of these vanilla flavors really bring something unique and different to the table. Especially that SA Vanilla Custard, I was going to sub CAP VC v1 since I have that already in my cart for another recipe. I don’t have any of the other 5 either so I will have to order all 5, unless I can condense them down…either way I’m looking forward to trying it.

On a side note I tried monster banana custard while I thought was highly regarded and thought it was a pretty mild flavor, just nothing punchy about it. Anyway thanks to all!
