Space saver tire in trunk, battery reocation

[super vw]

Hey guys, i was looking at ways i could get the battery up in the trunk, to help with weight distribution. but i still would like to have a spair tire "just in case" when im on the street.
So i stuck the battery where i wanted it (As low as possible) and then took my dady Space saver tire out of his 911 (as i will be runing 130/5 lug pattern)
and looked at ways i could mount the battery down, aswell as the spair.

What i came up with was a pedistal idea... what it would be is a pedistal from the tire well, that mounts the spair at an angle to clear the battery bellow.

Here are some pics of the idea (Note:i used some bar to test my idea, this is not how it would mount, the posistion would be almost the same though)

Would this be a good idea?
