If possible move to 10g, but 15g is all right I suppose.
Get rid of log hides. Get two of those half coconut hides, should be able to find them at petco/petsmart, and put one at the cool side and one at the warm side with the water bowl in between. Take two or three newspapers and crumple them up, so the bp will feel more secure. After a week try to feed a live hopper.
