Optimizing SMT footprints (0603 and 0402) for hand soldering

I am working on a project where I need to use 0603(1608 Metric) and 0402(1005 Metric) due to space constraints. My hands are not as steady as I want them to be. I have bought a stereo zoom microscope and a good soldering station. I have 0.020" solder wire and 0.010" is on the way.
If I increase the size of toe in footprints to give me more room, will it help?

Yes, but bigger pad means more space for misalignment, so your board won't look as "aligned" and "tidy" compared to commercial boards.
Also, you can't rewflow a board with excessively large pads due to the tendency of tombstoning.
