configuration question/issue - multiple unconsolidated sitemap visibility providers

[snowfire20]

Is it possible to have multiple sitemap visibility providers configured separably?
In our solution I have this configured with one custom provider as the default provider, and would like to also configure a completely separate provider(s).
we are using autofac as our Di container.

the "default" provider works perfectly, the other provider errors out like its not configured properly (same namespace)

more details and code snippets here: (apologies for posting in both places)
