You could do a fore and aft rod on each side running alongside, parallel, inboard the pipes ... with two clamps at the end of each side to support it without a rear muffler support ... that should be enough to support it ... as long as you didn't go too far aft or use mufflers that are too heavy ...
... like so ...
... maybe go further aft than forward ... thinking out loud here ....

SURFOR,
Where you show transmission mount in your diagram, I used the "Rear Isolator". It is very convenient and it is not necessary to weld to it though I did. The outer portion of the rear isolator is what is attached to the transmission. It is shaped in such a way that a bracket could be clamped to it, giving it a very universal application.

Just thought of something. All 2009 and newer Electra-Glides were recalled because the rear brake switch was too close to the cross-under pipe. I wonder if V&H is including the new brake switch, because it will melt and fail on the Dyna. I moved mine away from there.

Alright ... if you were adapting Softail true duals you could try something like this ...
... looks like the primary side would have to give more cantilever support for the weight back aft ...
... would need to get the bent shift lever to clear the pipe ...
... to yield a look something like this ...
... or maybe this ...

... also, the primary on Dyna and Softail are same size/shape (used to be interchangeable) ... so, I think the pipe would follow along the same on the Dyna ... maybe you could even just affix the Softail bracket to the end of your crossbar support ...

Eureka ... that may be the solution right there ... just make a crossbar that would accept both right and left Softail brackets ...

One of my father's bikes is a '98 FLSTS Heritage Springer with a spare exhaust system. He says he is putting it on his 05 FL-Dyna project bike and expects no real problems with the fit behind the rear cylinder. He is going to use an H bracket similar to your design; right side connected to tranny cover, left side to primary cover with a cross brace connected to the rear isolator.
