My upstream ISP does not support IPv6

You don't need a new BGP session to turn on IPv6, you just need to
enable IPv6 NLRI on your V4 session.. 

So, in theory your upstream can enable IPv6 on their side and then
wait until you are ready.. It helps to have a IPv6 address on the
link, but it does not need to carry the the BGP session over IPv6..

This is a feature that also simplifies your IBGP..
