As a premeditated exercise you might get round 180 degrees from below 500' and make a safe EOL (if there is a suitable landing area). However, in the real case where it takes a second or two to recognise the failure and react you are poorly placed.
As to downwind EOLs .. in 5-10 kts maybe but in 20 - 30 kts fat chance especially as it will be something you have never seen before.
You need to practise LL autos and EOLs a lot to have any chance of surviving and your choice of landing areas is very limited - don't kid yourselves that this is a realistic risk to take when deciding to press on in poor wx.
