If it was me then I would go for a modified version of option 2.
EGBM - Wrexham - Amylwch - EGNS, staying to the south of Hawarden and the Class A.
Ive flown to EGNS a few times, but always from the north so its the relatively short crossing from Burrow Head. Plus I've had the advantage of a few more knots than you.
One thing I did learn the hardway is that if the wind is from the east the clag can rollin very quickly. I mean VERY. Our day turned from CAVOK to 100m vis in about half an hour. Waited it out and just managed to leave at IMCR minimums with 1.5 hours day light left and a one hour flight.
Made me realise that the IMCR wasnt just about getting back down. Without it I would have been spending the night on the island.
Oh and if you are parking on the south apron make sure you have got transport arranged in advance. Taxis were reluctant to come round there and its a long walk to the main road/terminal.
