Dont know how interesting this is but recently i have seen an overbet used on river on a board like the one in this hand (AAxxx, KKxxx - not four to a straight though) five times. Four of the times the bettor had the nut boat. In the last hand I dont know what he had because I folded the underboat.
I haven't seen this play made with trips or as a bluff.

These hands were played at 1/2, the players aren't spirit rock...
