Instead of trying to find ways to make it easy to swap out a fried component, you really should be spending that effort trying to figure out why it's frying and add protection measures to just stop it happening instead. Frankly, if you have to replace mosfets on a regular basis, that's a clear indication that your circuit is just plain badly designed. If your problem is back-EMF or voltage spikes, an extra shunt diode or zener to protect the mosfet is likely all that's really required.

I like how despite your beliefs you still offer advice. Kudos
