Using gloves to fight numb hands is not a very good approach as it is not addressing the root cause. I mostly ride without gloves and it is more comfortable than with gloves.
Your saddle position is supposed to position you ideally above your pedals, not to modify pressure elsewhere, so it is an equally poor approach to hand issues.
I recommend finding an expert bike fitter in your area and taking your concerns there to get properly adjusted, rather than messing around with changes that could introduce other issues.
If this cannot be achieved to satisfaction on your current bike with the same parts or replacement stems/bars, then you should at least get the geometry measurements allowing you to shop for a more suitable frame.
