question about delsym cwe's

I was wondering if doing a 4 oz extraction is possible and how also  i have 2 different bottles of delsym both different flavors with like 1 2 oz in them is it fine to just mix them for the cwe? ive done dxm a lot and cwes alot but never done something like this and I cant post on the dxm sub because someone was buying delsym for like 20 dollars and was running low on money from that so I said to just take them which in retrospect was a bad choice but its just what I do anyways any help is appreciated thanks
