Discussion on question by Alex Cannon: How hard is it to disable or adjust a seat belt load limiter to improve safety?

It seems absurd to me that random internet people will be able to give you advice to improve the safety of your car more than the auto manufacturer has already done. No, you should NOT attempt to adjust or modify the restraint systems in your vehicle. If you are concerned that yours is unsafe, get rid of it and buy another one that has the sort of safety rating you are looking for. Some manufacturer advertise their safety qualities.
