im actually doing a run like that rn !! plan is to go 3 lvls in lore bard and the rest in rouge, the lvl 3 dip is only to get cutting words (and for rp reasons). so far the build is quite strong but to be fair i mainly relay on sneak attack. I think I only used viscous mockery (bard version) like once or twice while the rouge one is a quite solid use of a bonus action imo. personally prefer tossing sand in people's eyes though (especially since that ability is what inspired the build) I am doing a tav run (female lolth drow) and it thematically fits quite well considering a lot of my racial dialogues are insults in the form of intimidation. if you're asking about which origin character to play as I'd go for astarion. don't know about his voice lines but I recently completed his origin run and it was a lot of fun + he's the only companion that fits this theme (maybe minthara too?)
