Believe me, you need to do deadlifts. Unless you've got a very, VERY serious injury if you think you don't need deadlifts you are sadly mistaken. You thinking you don't need deadlifts makes me think you really need them a whole bunch.
If you just hate deadlifts because you suck at them, try figuring out which you suck at less between conventional and sumo. Then work on progressing your least sucky deadlift variation from a partial ROM movement to full ROM (so, for example, you could start pulling from high blocks or pins and work towards lowering their height until you can pull off the floor). You could even try trap bar deadlifts if you have access to a trap bar. If holding onto the bar is an issue because your grip strength is non-existant, there is nothing wrong with using straps while you do work to improve your grip.
If you have a serious injury preventing you from deadlifting, then you have my sincerest sympathy and I would suggest replacing DLs with remedial work with the goal of being able to do some form of deadlift safely in the future.
