With that load your climb performance is a couple hundred feet a minute....if that.
The slightest downdraft will put you in the rocks.
Reminded me of this accident:

Spot on, the report mentions 10520 ft DA and a rate of climb IF flying at VY of 270 fpm. They overflew a point at 25m - roughly 80ft - then turned and UNDERflew cables and then crashed.
