[TowerTalk] Raised Radial Spacing

I have a SteppIR BigIR vertical that I am refurbishing.  It will be installed in a small backyard that does not allow for the normal ground radial system (such as 60 ea at 33').  I will need to go to 2 ea tuned elevated radials for each band (80 thru 10 - 8 bands).  My solution (I think the only one I have due to lot restrictions) is to run the radials along the vinyl fence.  The vertical is mounted on a 4x4 post at 5 feet above the ground.  One direction has about 70' of length (straight) but the other direction has a 90-degree turn about 20 feet down from the antenna and then a straight shot the rest of the lengths so the radials for 80, 40, and 30 will have a 90-degree bend at that point and then continue on straight.  All the radials will follow the fence line so they will not be spaced out is a circular distribution from the antenna.  There will be about 1 to 2 feet of horizonal spacing in the plane for 4 bands (80, 40, 30 and 20).  I will do a similar install for the 17, 15, 12 and 10m bands but will have them be 1 to 2 feet down vertically from the 1st set of radials.  Hopefully, this is clear and not confusing - I do not think I am able to post a diagram of what I want to try.

Couple of questions:

Will this work?

What is the minimum spacing horizontally and vertically for the radials as proposed?

Any other suggestions?

Thanks,
