It has been said a few times that this will never happen (I asked too). It is too expensive and a huge hassle for them to do that. I've never found any vendor willing to do it with cartos. It seems the only places that have build-your-own samplers are juice vendors.
Just my $0.02 here: I'm wondering if it might not be cheaper for SI to place the 5 cartos in a single zip-loc bag like the business cards come in (only smaller, maybe) instead of the blister packs. Personally, I find that when I pop one carto out of the blister pack, I often break the foil on one or two adjacent cartos, thus ruining the seal.
At this point in my "vaping career", I'm still playing round-robin with numerous prefilled cartos and sampler bottles of juices. I've taken to placing the "dry" cartos for each favor in small zip-loc bags I have left over from my dart flights and shafts, until I refill them (usually a week or so later).
Another point: small resealable bags can often be re-purposed around the house; used blister packs not so much...
