re solid state relays..For the uninitiated -solid state relays come in two flavours:
1. Those for AC operation -  totally unsuitable as they employ TRIACs.
2. Those for DC operation, but read these guidelines from the leading manufacturer

They seem to be rather bulky nevertheless.
Last but not least - there's the intrinsic Diode of that MOSFET rendering the whole thing useless for the intended purpose!

Here's  circuits that make sense for high loads, minimal drop, and showing neglegible reaction time
