Since the tower is a radiator with a half sloper, probably connecting the end 40m elements to the boom would be good. This should be easy to model. I am not sure of a way to bond the tower sections but perhaps the connection is fine the way it is.
An easy option would be vertical dipole with the ends pulled out into a C shape. The downside is you may not like the lower wire running across your backyard unless it could be along the privacy fence.

Due to the 5 x sections overlapping, the feed point would have to be at the very top of the tower. IE: it can't be part way down from the top. Will it work with some top loading, like a 3 el 40m yagi ? Right now, my modified F12 340N yagi has all 3 x els insulated from the boom. ( oem LL wire loading replaced with hb 3/8" tubing coils). I was seriously thinking of bonding the REF and DIR to the boom, to increase the top loading. REF is aprx 59' long. DIR is aprx 52' long. I can't shunt feed the tower, since grnd mounted radials are out of the question. House is blocking the path of any radials > 180 degs.
