There's no real rule of thumb for changing the feed type and how that affects the antenna.
There are the obvious differences: for instance if you have a patch fed from underneath by a coaxial cable, then it is difficult to feed at the exact same spot with a microstrip transmission line (will need to cut away the edges so the transmission line enters the patch at the correct point) |
