I have a small layout and am running DCS with a new Rev L TIU.  I know, and have used, the “star” wiring method with each lead going to a single isolated block in previous layouts.  I am now using a small dog bone on carpet and and I would like to run two power feeds, one to each end, without making the dog bone into isolated blocks.  I realize that this "may" cause DCS communication problems, but I want to try it.  My question to those with more knowledge and experience with DCS is, will trying this pose any risk of damaging the TIU or an engine?  I would think not, but would like to hear the voice of others more experienced with DCS than I.

No damage. Try it!

If it struggles to communicate, break the loop of track in one spot so that the signal doesn't double back on itself. The 2 wire sets on each end may actually make this worse. That may force you to make blocks.

Why go back to DCC when I have DCS!

I'd say go ahead and try it. Never hurt any of my equipment. Before I learned how to properly wire for a DCS system (thanks to Barry's book), I had 2 or 3 temporary layouts wired with one or two power feeds and no blocks. Didn't hurt any of the equipment, but I got lots of DCS errors. I also have a Rev L TIU.
