clever ideas for a lightweight strut attach

This should get some of your winter doldrum brain juices flowing...

Anybody have any good ideas for a lightweight but strong way to get
around the lower spar caps on an aluminum strut braced wing?

Assume a 1.5" wide t-cap. The heavy way is to add two strut attach
straps and two 3/4" spacers with thru-bolts.

Ideally it would be best to rivet (vs bolt) the attachment to keep the
stress distributed to all of the elements rather than causing the bolts
to be put into bending (from the elements being disconnected).

Without going to a relatively complex machining (or machined spacer) do
you all have any ideas for transferring this load into the web and caps
without a lot of weight?

Thanks.
