I wonder instead of lobbying against it, lobby for posted bike signs and education? It would be easy to post suggested speed limits and bike signs and "bikes take lane" (or whatever would be appropriate) in the roundabout entrances?
I agree, I'm not so sure about the safety of the design of your particular roundabout with dual lane entries and single lane exits.

And well-designed signage and education programs could go a long way.

It might be worth your while to do some research to find out what safety/accident statistics exist for roundabouts similar to the one proposed in your community, and at the same time look for some design strategies, whether it be signage, an education program, or a different lane configuration, that might improve bicycle safety in this case.

I would also hope that your DOT/traffic engineers would also have some good data regarding vehicle speeds during peak traffic flow vs. speeds during non-peak times. Overlaying that with what you know about how the number of cyclists using the intersection varies throughout the week might provide valuable insight for all parties.
