Just to be clear the “main” work you do will give you some 90-95% of your training effect. If this isn’t on point no amount of special techniques, finishers or exercise variations will make up for it.
What you suggested would likely have a similar effect to an extra work set or two tops. So not much of a training effect.
If it’s to give your body/joints extra stimulus while giving it a rest from big weights sure, but you may as well do more working sets over time if it’s within your work capacity. The stimulus or what “spurs” muscle growth is still progressive overload e.g. more volume, more drugs, more weight etc.
