Can i keep the stock rims and go 27 x 10 x 14s on all fours?
A lot of people do it so yes, you can, but just know the wider wheel will make the overall diameter different from the narrower wheel. Not much depending on the tire construction..most times only an 1/8 to 1/4". And just know that makes them spin at slightly different rates. In 2wd it just means the front drive line is spinning at a slightly faster rate then the front pinion but lock it in 4wd and the two not being the same means one had to build up the torque and release bu slipping the tires. That's OK in soft stuff but in pavement or hard pack the tires won't slip as easy and that torque builds higher putting more pressure on the ring and pinion until the tires do slip...or the worst case scenario, the case cracks. Just don't be in 4wd on pavement or any material where the tires have a hard time releasing that stress. Do it, air them up to what you will be running, then use a drywall square and small square to measure them both. If you are 1/4" or less, probably won't have a problem. But if more...consider a set of wheels in the future.
Lay them on the ground, no weight on them and measure from the center of the tread (that why the square) across the center of the wheel to the other side like this on one front and one back.
