Yes, you can skip the patch panel and crimp the cable to a standard RJ45 Plug and connect to the Network Switch. This will help to save some cost. However there are a few points to consider if you intend to skip the patch panel.
Installation cables are constructed with solid core copper. Doing field crimping to a RJ45 Plug has a higher failure rate and time consuming.
Solid core cables are stiff which would be inconvenient to use with a switch. Too much bending when tiding the cables neatly may cause more trouble in the future.
If you change a switch location, the cable may not be long enough to connect to the switch.
If you are laying the cable for future needs and you are not pluging into the switch due to limited switch port, it will be dangling and messy.
Yes you can but take note, the diameter of the CAT6 cable cannot be too thick and the copper guage must be around 23AWG to 24AWG. If not you will have problem inserting the cable into the CAT5e Plug. Another thing to take note is that if you are certifying a CAT6 network cabling system with a Cable Analyser, you may not pass some of the CAT6 perimeter test.
