Probably but I suggest you research benzos more before diving into them. Especially since one (Flub) is a RC and not controlled substance like Alps. Could be a fun time, or a blackout, ER visit; wake up in jail situation.
IME a large dose of Flub made me mashy and falling over myself. I can't imagine adding Alps to it. Also how do you define "bad trip". Psychedelics? Dissociatives?
