Doubt it, unless you can maintain about 15kn SOG! It is nearly 30 miles, and the gate closes at Watchet about 2hrs after HW Avonmouth IIRC. It is hard enough to do in a sail boat, even if you leave before HW to punch the tide down to Clevedon. There is a good anchorage at Blue Anchor Bay, only a couple of miles away, to wait until the next opening time. The advice is to approach Watchet just before HW
