... and now you have two (probably unsolveable) problems instead of one.  

In addition because the second problem virtually never occurs, it'll receive 
little or no evaluation in the real world, and will either not work when it's 
needed or will break when it's not needed, allowing your main PKI to be 
compromised through it.
