This place is great and everyone is super helpful. So on to your question.
Yes you should be able to. I would suggest making a ganache dam around the edges to hold the jam in. Put that in the fridge for a little bit to get the dam to hard so it doesn’t shift while trying to ganache the outside.
Welcome to CD and I agree with Jennifer, you will get all the help you want here :-) Everyone is so nice and ready to give advice.
I also agree with Jennifer on securing the jam inside with a first cover of ganache and have that chill, then applying your second coating.
