Battery in trunk/ fastback?

I`m thinking of moving the battery to the trunk in my 68 Barracuda fastback. The car is a street car so I have my bumper jack and spare in the trunk still and would like to keep it there. I`d like to move the battery to the right rear. My problem is that, if I move the battery to the trunk, I have to move it to the left side because the right side is occupied by the jack. If I put it far enough out that I could access the jack the fold down door in the trunk won`t open. Does anybody have their battery-in-trunk on the left side? Would this be okay?
